Subject: Re: [dita] Improving variable content in 2.0

Joe is right that <linktext> is meant to be a general best practice there, and will work for all elements that pull in text using @keyref -- provided you use the latest DITA-OT release. The toolkit did not properly resolve text for all cases using <linktext> until the 2.5.1 release a few weeks ago.

Hi Scott,

Elsewhere the spec suggests using the <linktext> element as a best practice "for cases where all elements getting text from a key definition should result in the same value":

I just tried it quickly and it appears to be legal per the DTDs and also work fine in the DITA-OT!

Here’s my map:

<title>DITA Topic Map</title>
<keydef keys="SomeKey">
<linktext>Some text string</linktext>
<topicref href="TestReferencingLinktextFromWintitle.dita"/>

And here’s the topic:

<concept id="topic">
<title>Test referencing linktext from wintitle</title>
<p>Wintitle follows: <wintitle keyref="SomeKey"/></p>

Is that helpful at all?

Best regards,

The current method for creating content variables is to use a keyword construct. (https://docs.oasis-open.org/dita/dita/v1.3/os/part1-base/archSpec/base/example-key-definition-for-variable-text.html )

For example:
<keydef keys="productname">
<keyword audience="GA">ProductA</keyword>

<keyword audience="BA">ProductB</keyword>
<keyword audience="CA">ProductC</keyword>

Unfortunately, keyword is not allowed in many content models, so you cannot use variables in many cases. Here's an example use case:
We have product names that are stored as variables (in case Marketing changes the name during development and due to product variants), which we express in DITA using <keyword> keys. Several of our user interfaces use the product name as part of the interface area, which should be tagged with wintitle.

Right now, we have no way of marking the following:
Unfortunately, the current model for <keydef> doesn't let you define variable content using ph or text elements, and the <wintitle> model, only (text data | <text>)* is allowed.

For DITA 2.0, I'd like to propose a more globally applicable method for including variable content, perhaps based on <ph> or <text>.

Thanks and best regards,
