From a news item the Debian project released at the beginning of May:

The upcoming stable Debian release (code-named sarge) will feature fully integrated XML support. Multiple toolchains for XSL(T) processing, a fully standards-compliant XML catalog system, and a Debian XML policy document for both Debian developers and users.

I reckoned the XML support in Debian testing was already pretty good, so not sure what all is new here. Mainly, maybe it’s not so much the tools, which were already in place, but other stuff, like the XML policy doc, packaging guidelines and a claim of FHS compliance.
