Do not filter sentence fragments
As described in the basic course on reusing elements, do not use filtering on anything smaller than a sentence.
It’s better to have two instances of an entire sentence that are grammatically correct (and will remain correct when translated) than to risk ending up with poorly constructed—or even non-sensical—sentences.
Communicate your choices
Create a style guide or some other form of documentation so that everyone on your team, organization, or company uses conditional attributes and values consistently.
Make sure you have agreement on:
- How and why everyone uses the audience, platform, product, and otherprops attributes.
- The precise values everyone uses with those attributes and the meaning of each value. Remember that case matters when comparing attribute values with the val attribute in ditaval file.
If there are not enough conditional attributes for your needs, or if the names of the attributes do not fit with how you are using them, consider using the DITA specialization mechanisms to create additional conditional attributes.
