Description:

A new XML Writer was needed to match the SAX2 effort because quite naturally
no existing writer understood SAX2. My first intention had been to start
patching XML::Handler::YAWriter as it had previously been my favourite writer
in the SAX1 world.

However the more I patched it the more I realised that what I thought was
going to be a simple patch (mostly adding a few event handlers and changing
the attribute syntax) was turning out to be a rewrite due to various ideas
I'd been collecting along the way. Besides, I couldn't find a way to
elegantly make it work with SAX2 without breaking the SAX1 compatibility
which people are probably still using. There are of course ways to do that,
but most require user interaction which is something I wanted to avoid.

So in the end there was a new writer. I think it's in fact better this way as
it helps keep SAX1 and SAX2 separated.
