+ *                   Style sheet for the W3C specifications                   *
+ *
+ * Special classes handled by this style sheet include:
+ *
+ * Indices
+ *   - .toc for the Table of Contents (<ol class="toc">)
+ *     + <span class="secno"> for the section numbers
+ *   - #toc for the Table of Contents (<nav id="toc">)
+ *   - ul.index for Indices (<a href="#ref">term</a><span>, in §N.M</span>)
+ *   - table.index for Index Tables (e.g. for properties or elements)
+ *
+ * Structural Markup
+ *   - table.data for general data tables
+ *     -> use 'scope' attribute, <colgroup>, <thead>, and <tbody> for best results !
+ *     -> use <table class='complex data'> for extra-complex tables
+ *     -> use <td class='long'> for paragraph-length cell content
+ *     -> use <td class='pre'> when manual line breaks/indentation would help readability
+ *   - dl.switch for switch statements
+ *   - ol.algorithm for algorithms (helps to visualize nesting)
+ *   - .figure and .caption (HTML4) and figure and figcaption (HTML5)
+ *     -> .sidefigure for right-floated figures
+ *   - ins/del
+ *     -> ins/del[cite] for candidate and proposed changes (amendments)
+ *
+ * Code
+ *   - pre and code
+ *
+ * Special Sections
+ *   - .note       for informative notes             (div, p, span, aside, details)
+ *   - .example    for informative examples          (div, p, pre, span)
+ *   - .issue      for issues                        (div, p, span)
+ *   - .advisement for loud normative statements     (div, p, strong)
+ *   - .annoying-warning for spec obsoletion notices (div, aside, details)
+ *   - .correction for "candidate corrections"       (div, aside, details, section)
+ *   - .addition   for "candidate additions"         (div, aside, details, section)
+ *   - .correction.proposed for "proposed corrections" (div, aside, details, section)
+ *   - .addition.proposed   for "proposed additions"   (div, aside, details, section)
+ *
+ * Definition Boxes
+ *   - pre.def   for WebIDL definitions
+ *   - table.def for tables that define other entities (e.g. CSS properties)
+ *   - dl.def    for definition lists that define other entitles (e.g. HTML elements)
+ *
+ * Numbering
+ *   - .secno for section numbers in .toc and headings (<span class='secno'>3.2</span>)
+ *   - .marker for source-inserted example/figure/issue numbers (<span class='marker'>Issue 4</span>)
+ *   - ::before styled for CSS-generated issue/example/figure numbers:
+ *     -> Documents wishing to use this only need to add
+ *        figcaption::before,
+ *        .caption::before { content: "Figure "  counter(figure) " ";  }
+ *        .example::before { content: "Example " counter(example) " "; }
+ *        .issue::before   { content: "Issue "   counter(issue) " ";   }
+ *
+ * Header Stuff (ignore, just don't conflict with these classes)
+ *   - .head for the header
+ *   - .copyright for the copyright
+ *
+ * Outdated warning for old specs
+ *
+ * Miscellaneous
+ *   - .overlarge for things that should be as wide as possible, even if
+ *     that overflows the body text area. This can be used on an item or
+ *     on its container, depending on the effect desired.
+ *     Note that this styling basically doesn't help at all when printing,
+ *     since A4 paper isn't much wider than the max-width here.
+ *     It's better to design things to fit into a narrower measure if possible.
+ *
+ *   - js-added ToC jump links (see fixup.js)

+    </p>
+    <ol>
+      <li>
+        A Core set of properties describing the generalized structure of an Activity; and
+      </li>
+      <li>
+        An Extended set of properties that cover specific types of Activities and Artifacts common to many social Web
+        application systems.
+      </li>
+    </ol>
+    <p></p>
+
+    <p>
+      While not all Activity Streams 2.0 implementations are expected to implement support for the Extended properties,

+      The Activity Streams 2.0 Extended Types include Activity and Object subtypes that are common to many social Web
+      applications. They are divided into three sets:
+    </p>
+    <ul>
+      <li><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#activity-types">Activity Types</a></li>

+      <li><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#object-types">Object Types</a></li>
+    </ul>
+    <p></p>
+
+    <p>
+      Support for specific extended vocabulary types is expected to vary, with implementations only selecting the
+      extended types and properties that make sense within the specific context and requirements of those applications.
+      However, to avoid possible interoperability issues, implementations <em class="rfc2119" title="MUST">MUST</em>
+      avoid using extension types or properties that unduly overlap with or duplicate the extended vocabulary defined
+      here.

+      The "Domain" indicates the type of Object the property term applies to. The "Range" indicates the type of value
+      the property term can have. Certain properties are marked as a "Subproperty Of" another term, meaning that the
+      term is a specialization of the referenced term. For instance,
+      <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-actor" class="internalDFN" data-link-type="dfn">actor</a></code>
+      is a subproperty of
+      <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-attributedto" class="internalDFN" data-link-type="dfn">attributedTo</a></code>.
+      Properties marked as being "Functional" can have only one value. Items not marked as "Functional" can have
+      multiple values.

+      </h3>
+
+      <p>
+        Conceptually, every Object has both a Primary and Secondary audience. The Primary audience consists of those
+        entities directly involved or owning the object. The Secondary audience consists of the collection of entities
+        sharing an interest in the object but who might not be directly involved (e.g."followers").
+      </p>
+
+      <p>
+        For instance, suppose a social network of three individuals: Bob, Joe and Jane. Bob and Joe are each friends
+        with Jane but are not friends with one another. Bob has chosen to "follow" activities for which Jane is directly
+        involved. Jane shares a file with Joe.
+      </p>
+
+      <p>
+        In this example, Jane and Joe are each directly involved in the file sharing activity and together make up the
+        Primary Audience for that event. Bob, having an interest in activities involving Jane, is the Secondary
+        Audience. Knowing this, a system that produces or consumes the activity can intelligently notify each person of
+        the event.
+      </p>
+
+      <p>
+        While there are means (based on the action type, actor, object and target of the activity) to infer the primary
+        audience for many types of activities, heuristics do not work in every case and do not provide a means of
+        identifying the secondary audience. The
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-to" class="internalDFN" data-link-type="dfn">to</a></code>,
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-cc" class="internalDFN" data-link-type="dfn">cc</a></code>,
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-bto" class="internalDFN" data-link-type="dfn">bto</a></code>
+        and
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-bcc" class="internalDFN" data-link-type="dfn">bcc</a></code>
+        properties <em class="rfc2119" title="MAY">MAY</em> be used within an Object to explicitly identify the Primary
+        and Secondary audiences.
+      </p>
+
+      <p>
+        The prototypical use case for an Object containing these properties is the publication and redistribution of
+        objects through an intermediary. That is, an event source generates the object and publishes it to the
+        intermediary which determines a subset of items to display to specific individual users or groups. Such a
+        determination can be made, in part, by identifying the Primary and Secondary Audiences for each object.
+      </p>
+
+      <p>
+        When the event source generates the object and specifies values for the <code>to</code> and <code>cc</code>
+        fields, the intermediary <em class="rfc2119" title="SHOULD">SHOULD</em> redistribute that object with the values
+        of those fields intact, allowing any processor to see who the object has been targeted to. This is precisely the
+        same model used by the <code>to</code> and <code>cc</code> fields in email systems.
+      </p>
+
+      <p>
+        There are situations, however, in which disclosing the identity of specific members of the audience may be
+        inappropriate. For instance, a user may not wish to let other users know that they are interested in various
+        topics, individuals or types of events. To support this option, an implementation generating an object <em
+          class="rfc2119" title="MAY">MAY</em> use the
+        <code>bto</code> and <code>bcc</code> properties to list entities to whom the object should be privately
+        targeted. When an intermediary receives an object containing these properties, it
+        <em class="rfc2119" title="MUST">MUST</em> remove those values prior to redistributing the object. The intent is
+        that systems <em class="rfc2119" title="MUST">MUST</em> consider entities listed within the

+          Activities are rarely isolated events. Often, multiple individual activities will be performed around a
+          similar context or audience. For instance, a collaborators working on a shared project might perform multiple
+          related activities in the process of achieving some goal. Such activities can be logically grouped together
+          using the
+          <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-context" class="internalDFN" data-link-type="dfn">context</a></code>

+        The
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-relationship" class="internalDFN" data-link-type="dfn">Relationship</a></code>
+        object is used to represent relationships between individuals. It can be used, for instance, to describe that
+        one person is a friend of another, or that one person is a member of a particular organization. The intent of
+        modeling Relationship in this way is to allow descriptions of activities that operate on the relationships in
+        general, and to allow representation of Collections of relationships.
+      </p>
+
+      <p>
+        For instance, many social systems have a notion of a "friends list". These are the collection of individuals
+        that are directly connected within a person's social graph. Suppose we have a user, Sally, with direct
+        relationships to users Joe and Jane. Sally follows Joe's updates while Sally and Jane have a mutual
+        relationship.
+      </p>
+
+      <p>
+        Using the
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-relationship" class="internalDFN" data-link-type="dfn">Relationship</a></code>
+        object, we can model these relationships as:

+        properties. Used together, these three properties form what is commonly known as a "
+        <a href="http://patterns.dataincubator.org/book/reified-statement.html">reified statement</a>" where
+        <code><a data-lt="subject" href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-subject" class="internalDFN" data-link-type="dfn">subject</a></code>

+        object together with the

+        Additionally, modeling the relationship in this way allows implementers to articulate additional properties of

+
+      <p>
+        Implementations may reuse existing vocabularies that have been developed for the purpose of describing

+        vocabularies include the "
+        <a href="http://xmlns.com/foaf/spec/">Friend of a Friend</a>" and "

+          One common use case for many social platforms is the establishment of symmetrical "friend" relationships, in
+          which one user initially extends a request to another user to establish a new connection. Once the connection
+          is made, both users automatically begin receiving notifications about activities performed by the other, and
+          the established relationship becomes visible in either user's "friends list".
+        </p>
+        <p>
+          The initial "friend request" can be modeled by composing the

+
+      <p>
+        Many social software systems use special text-based microsyntaxes that allow users to define special addressing
+        for notifications, linking, or categorization within objects. For example, including text such as
+        "<code>@username</code>" within an object's content will often route the object to a special "mentions" or
+        "inbox" stream for a particular user. Likewise, including text such as "
+        <code>#topic</code>" within the object's content will often mark the object as being related to the topic
+        "<code>topic</code>". Such mechanisms are commonly referred to as "mentions" and "hashtags", respectively.
+      </p>
+
+      <p>
+        While such microsyntaxes <em class="rfc2119" title="MAY">MAY</em> be used within the values of the
+        <code><a data-lt="content-term" href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-content" class="internalDFN" data-link-type="dfn">content</a></code>,
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-name" class="internalDFN" data-link-type="dfn">name</a></code>,
+        and
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-summary" class="internalDFN" data-link-type="dfn">summary</a></code>
+        properties on an Activity Streams
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-object" class="internalDFN" data-link-type="dfn">Object</a></code>,
+        implementations <em class="rfc2119" title="SHOULD NOT">SHOULD NOT</em> be required to parse the values of those
+        properties in order to determine the appropriate routing of notifications, categorization or linking between
+        objects. Instead, publishers <em class="rfc2119" title="SHOULD">SHOULD</em> make appropriate use of the
+        vocabulary terms provided specifically for these purposes.
+      </p>
+
+      <p>
+        For example, suppose that an author wishes to send a note of thanks to another user named "@sally" with a
+        hashtag of "#givingthanks". A typical way this message would appear within the content of a note is shown below:
+      </p>
+
+      <figure id="fig-a-simple-note-with-a-mention-an-a-hashtag">
+        <figcaption>Figure <span class="figno">1</span> <span class="fig-title">A simple note with a mention an a
+            hashtag:</span></figcaption>
+        <pre aria-busy="false" aria-live="polite"
+          class="hljs css"> "<span class="hljs-selector-tag">Thank</span> <span class="hljs-selector-tag">you</span> @<span class="hljs-keyword">sally</span> for all your hard work! #givingthanks<span class="hljs-string">" </span></pre>
+      </figure>
+
+      <p>
+        A typical social software implementation would typically render such a content such that "<code>@sally</code>"
+        is replaced with a hyperlink to "@sally"'s social profile page and "<code>#givingthanks</code>" is replaced with
+        a hyperlink to a listing of other notes that have been "tagged" with the same topic. Most implementations would
+        also send a special notification to sally letting her know that a note mentioning her has been created.
+      </p>
+
+      <p>
+        The following illustrates an equivalent Activity Streams
+        <code><a href="https://w3c.wholetrans.org/activitystreams-vocabulary/#dfn-note" class="internalDFN" data-link-type="dfn">Note</a></code>
+        object:

+        The <code>to</code> property indicates that the user "@sally" is to be considered part of the <a
+          href="https://w3c.wholetrans.org/activitystreams-vocabulary/#audienceTargeting">primary
+          audience</a> of the note and should therefore receive notification. The
+        <code>tag</code> property associates the Note with a reference to "
+        <code>http://example.org/tags/givingthanks</code>". Note that the
+        <code>content</code> still includes the "<code>@sally</code>" and "
+        <code>#givingthanks</code>" microsyntaxes but that consuming implementations are not required to parse those in
+        order to make the appropriate associations.

+
+      <p>
+        In the case a publisher wishes to indicate a mention without an associated notification, the publisher can use
