Example: Resolving conrefs to elements that contain cross references, with key scopes

This section is non-normative.

In this scenario, elements referenced by conref include cross references using a variety of referencing styles. The topics themselves are used in a map that makes use of key scopes.

Consider the following paragraphs in paras-01.dita that are intended to be used by reference from other topics:

<topic id="paras-01">
    <title>Reusable paragraphs</title>
    <body>
        <p id="p1">See <xref href="#paras-01/p5"/>.</p>
        <p id="p2">See <xref href="topic-02.dita#topic02/fig-01"/>.</p>
        <p id="p3">See <xref href="#./p5"/>.</p>
        <p id="p4">See <xref keyref="task-remove-cover"/>.</p>
        <p id="p5">Paragraph 5 in paras-01.</p>
    </body>
</topic>

The paragraphs are used by content reference from other topics, including the using-topic-01.dita topic:

<topic id="using-topic-01"><title>Using topic one</title>
    <body>
        <p id="A" conref="paras-01.dita#paras-01/p1"/> 
        <p id="B" conref="paras-01.dita#paras-01/p2"/> 
        <p id="C" conref="paras-01.dita#paras-01/p3"/>
        <p id="D" conref="paras-01.dita#paras-01/p4"/>
        <p id="p5">Paragraph 5 in using-topic-01</p>  
    </body>
</topic>

Now consider the following map, which uses each of the topics above:

<map>
  <topicgroup keyscope="product-1">
    <topicref keys="task-remove-cover" href="prod-1-task-remove-cover.dita"/>
    <topicref href="using-topic-01.dita"/>
  </topicgroup>
  <topicgroup keyscope="product-2">
    <topicref keys="task-remove-cover" href="prod-2-task-remove-cover.dita"/>
    <topicref href="using-topic-01.dita"/>
  </topicgroup>
</map>

The map establishes two key scopes: "product-1" and "product-2". Within the map branches, the key name "task-remove-cover" is bound to a different topic. The topic using-topic-01.dita, which includes a conref to a paragraph that includes a cross reference to the key name "task-remove-cover", is also referenced in each branch. When each branch is rendered, the target of the cross reference is different.

In the first branch with the key scope set to "product-1", the cross reference from paragraph p4 is resolved to prod-1-task-remove-cover.dita. In the second branch with the key scope set to "product-2", the cross reference from paragraph p4 is resolved to prod-2-task-remove-cover.dita.
