There are so many more developers who use XML than who write XML parsers 
that the cost of writing a parser is negligible when spread over the 
number of users. A small increase in the usability of XML is worth even 
the cost of a major increase in the complexity of writing a parser. We 
should not be aiming for a world where everyone writes their own parser. 
No matter how easy it is to do, developers will get this wrong the first 
few times out the gate. The resulting practical subsets and supersets of 
XML would be an interoperability nightmare. We're better off with fewer 
parsers written and debugged by experts, rather than everyone writing 
their own custom one-off parser.
