Might I suggest 4Suite Server?  We're finalizing version 0.10.3 (probably out 
on Monday), which will even have a complete API for XML repository queries 
from XPath.  Imagine doing your XML repository operations from good ol' XSLT.

Anyway, the version 0.10.3 release will also support XPath, XSLT, RDF, XLink, 
XPointer, XInclude, HTTP, WebDAV, and limited SOAP right in the repository.

It's implemented in Python, but it can be accessed from the command line 
(Windows or UNIX), XSLT, HTTP, as well as Java, C++, Perl and any other 
language via CORBA.

The back-end XML storage can be PostgresQL for efficient and scalable storage.

And look out for the 0.10.3 release announcement on this list early next week.
