I have always been of the opinion that, at least for certain classes of 
documents, validation could be used to speed the process up. If certain 
VCs were considered fatal errors, then character checking would be 
reduced for start tags (i.e., instead of checking that a character is a 
valid XML character, you would check if the name is valid according to 
the DTD). This would mean that in situations where an element was 
repeated the XML character checking could be avoided. In situations 
where the DTD could be cached you would gain a more substantial speed 
increase.

Now, let me be the first to say-- I wouldn't want to see VCs treated as 
fatal, I wouldn't want to require DTDs, and I haven't actually tested 
this... it is only conjecture.

Cheers,
