Unicode, not ASCII. Never forget that. An XML processor is a complex piece of 
software since it *must* operate at the Unicode level (even if it's just 
mapping some ASCII variant to Unicode) to be able to process valid XML 
documents, which may contain character references to Unicode, or be encoded 
in UTF-8.

Yeah!

Yeah!
