You'll need to extend the XMLContentAssistProcessor class, and possibly 
override the element completion methods, so that it looks up the values 
that correspond to your key and keyref values.  You may also need to add 
a sourceviewer configuration that tells it to use your content assist 
processor as well as the default content assist processor.
