Example: References to scoped keys

You can address scoped keys from outside the key scope in which the keys are defined.

<map xml:lang="en">
  <title>Examples of scoped key references</title>

  <!-- Key scope #1 -->
  <topicgroup keyscope="scope-1">
    <keydef keys="key-1" href="topic-1.dita"/>
    <topicref keyref="key-1"/>
    <topicref keyref="scope-1.key-1"/>
    <topicref keyref="scope-2.key-1"/>
  </topicgroup>

  <!-- Key scope #2 -->
  <topicgroup keyscope="scope-2">
    <keydef keys="key-1" href="topic-2.dita"/>
    <topicref keyref="key-1"/>
    <topicref keyref="scope-1.key-1"/>
    <topicref keyref="scope-2.key-1" />
  </topicgroup>

  <topicref keyref="key-1" />
  <topicref keyref="scope-1.key-1" />
  <topicref keyref="scope-2.key-1" />

</map>

For this example, the effective key definitions are listed in the following tables.

Table 1. Effective key definitions for scope-1

Key reference	Resource
key-1	topic-1.dita
scope-1.key-1	topic-1.dita
scope-2.key-1	topic-2.dita

Table 2. Effective key definitions for scope-2

Key reference	Resource
key-1	topic-2.dita
scope-1.key-1	topic-1.dita
scope-2.key-1	topic-2.dita

Table 3. Effective key definitions for the key scope associated with the root map

Key reference	Resource
key-1	Undefined
scope-1.key-1	topic-1.dita
scope-2.key-1	topic-2.dita
