DITA v1.2 Review | @keys in a conref

[Tarun Garg <tarung@adobe.com>]

I am not able to identify the use of @keys at an element that is actually a conref. In case of a conref, the @href may be generally missing as that shall be derived from the referenced element.

 

Say for example, in a map there is topicref element which is actually a conref to a topicref element in another map.

 

In map1.ditamap:

<map>

         …….

         <topicref id=”tr-01”  keys=”TR01” href="”abc.dita”/>

         …….

</map>

 

In map2.ditamap:

<map>

         …….

         <topicref id=”tr-02”  keys=”TR02” conref=”map1.ditamap#tr-01”/>

         …….

</map>

 

What shall the key TR02 resolve to? As I understand, that resolves to nothing.

Also, is there any specific use of such a key in a conref element, apart from defining a key that points to nothing. I am not ruling out the cases where such an element carries an @href as well. But in that case, the purpose of conref is undermined.
