XML References

I have been doing a bit more housekeeping. Here is a collection of some general XML references found over the last few months.

XML.com
Transforming XML (Column)
IBM developerWorks XML
PerfectXML
The Annotated XML 1.0 Specification
XML Bible - Schemas
XML Bible - XSL Formatting Objects
XML developer news from XMLhack

I have also found the O'Reilly book Java and XML a great starter.
