Yeah. Some people take this and argue that it's allowed for the  
application to take the unprocessed input and continue to build on the  
parsed tree with error recovery. While this is technically not against the  
letter of the spec, it is black-box equivalent to a non-compliant "XML  
processor" that does error recovery.

Obviously.

I won't argue with that, but I stand by my statement that some folks want  
error recovery to the extent that they snip implementations with error  
recovery.

You can define error recovery so that such implementations can  
interoperate with each other while stating that it is allowed to abort so  
that folks who don't want error recovery aren't forced to do it.
