A few hundred downloads, one substantial contribution from Nigel 
Whitaker.  It's not actually a SAX filter - it works on the stream or 
reader before it hits the parser, since the parser itself uses the 
DOCTYPE.  Should work with any Java-based parser, DOM or SAX.

In most of the XML I've seen, people aren't using DOCTYPE at all.  A lot of 
people who do use DOCTYPE seem to do so because the word 'valid' suggests 
that merely-well-formed is invalid.

Then there are, of course, the people who take DOCTYPE, Schemas, etc. very 
seriously.  In terms of news stories, they're the ones we really hear 
about, but I'm not convinced that they are the majority.
