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, Jeff Rafter
