I would almost rather try to harmonize the rules between XHTML and HTML 
if that's possible.  For example, by declaring that in HTML and XHTML 
family documents CURIE prefixes are case-insensitive.  This would be a 
significant change from the current recommendation, but I think it is 
unlikely that this change would actually adversely effect the triples 
generated by any existing pages.  If a change like this needs to be 
made, obviously it should be made sooner than later.
