Examples: Key definitions for variable text
Key definitions can be used to store variable text, such as product names and user-interface labels. Depending on the key definition, the rendered output might have a link to a related resource.
In the following example, a "product-name" key is defined. The key definition contains a child keyword element nested within a keydefelement.
<map>
<keydef keys="product-name">
<topicmeta>
<keywords>
<keyword>Thing-O-Matic</keyword>
</keywords>
</topicmeta>
</keydef>
</map>
A topic can reference the "product-name" key by using the following markup:
<topic id="topicid">
<p><keyword keyref="product-name"/> is a product designed to ...</p>
</topic>
When processed, the output contains the text "Thing-O-Matic is a product designed to ... ".
In the following example, the key definition contains both a reference to a resource and variable text.
<map>
<keydef keys="product-name" href="thing-o-matic.dita">
<topicmeta>
<keywords>
<keyword>Thing-O-Matic</keyword>
</keywords>
</topicmeta>
</keydef>
</map>
When processed using the key reference from the first example, the output contains the "Thing-O-Matic is a product designed to ... " text. The phrase "Thing-O-Matic" also is a link to the thing-o-matic.dita topic.
