The fourth incarnation of Microsoft's XML tools, MSXML
4, has been released as a "supported, production quality"
release.
Improvements over the previous release, MSXML 3.0, include:
- Support for W3C XML Schema Recommendation
- Faster XSLT processing
- Faster SAX parser
- Removal of some none-standard legacy features (e.g. old
version of XSLT, uuid namespaces in XDR)
It is possible to run MSXML4 in parallel with existing, or future,
versions of the software.
