Help adding @processing-role to XDITA map DTD

Dear Lightweight DITA SC members,

I need help with a couple of items related to adding @processing-role to topicref in XDITA.
1- @processing-role actually exists as an attribute of keydef in the XDITA map mod. It is a fixed att with value of 'resource-only.' We need to declare it for both elements now.
2- What values should @processing-role have as attribute of topicref? In 1.3 we have normal, resource-only, and -dita-use-conref-target. I assume that the conref target is a no-no value in XDITA, right?

This is the only change missing before we can build the new package for TC vote next week... so I will appreciate anyhelp/volunteers to update the DTDs. 

Best,

Carlos
