Apache Releases Xerces 2.0 XML Parser
GeneOff writes: "Xerces 2.0 is out! You can get it here. This XML parser features full XML Schema conformance and partial support for DOM Level 3. The XNI (Xerces Native Interface,) is very cool. Xerces is arguably the most widely deployed Java based XML parser. Open source projects like those from Apache do a very good job of tracking upcoming standards like XML Schema (no more weird DTDs.) Kind of like Linux 2.5 and the USB 2.0 spec."
Dont know about the others, but when I write a spec, I do it in DTD, then convert to XML Schema and add missing features.
From then on, the XML Schema version servers for me as a format to validate against while DTD is the format at which I look to refresh in mind the structure.
Tastes differ ;-)
