Agreed. I am on the fence with the judgement call, which is why I am  
interested in the opinion of the readers of this list. It has been  
suggested to me at least twice in private that I could consider not  
supporting xml:id at all (i.e. emit an error even). However,  
supporting xml:id is not that hard, since I already added an xml:id  
processor to the processing pipeline so anything keyed on IDness just  
works. (For referential integrity checking, I changed the Schematron  
assertions to use XPath id() and I am writing Java code that looks  
for IDness rather than the name "id".)
