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.
<topicref id="tr-01" keys="TR01" href="abc.dita"/>
<topicref id="tr-02" keys="TR02" conref="map1.ditamap#tr-01"/>
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.
