That's fair enough - I think I was trying to be more charitable to 
parser writers. Attribute value normalization certainly causes problems 
when trying to parse XPath from an attribute value and give good error 
locations.

However I would say that reporting accurate line and column numbers has 
very little to do with performance, as I've been able to write a parser 
with roughly the same performance as expat that does just that.
