It is hard to say what the correct behavior is since the id value is a  
document conformance error (for HTML4.01 and XML 1) so the correct  
behavior would be regarding error recovery which I don't think anyone  
has specified. Part of what Erik’s bug submission[1] seeks to address  
relates both to what authors specify for IDREFs and how UAs handle  
pointers to document fragments (including pointers involving IDREFs).  
Obviously it would make sense for the HTML WG to address these issues,  
but for some reason this is a taboo topic and the bug has to be closed  
immediately without proper resolution.

Take care,
Rob
