Examples: Key definitions for variable text

This section is non-normative.

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 <keydef>element.

<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">
  <title>...</title>
  <body>
    <p><keyword keyref="product-name"/> is a product designed to ...</p>
  </body>
</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.
