Dropping into this discussion relatively late..

I've done a lot of work in this domain. I can map a single XML document
to a single IIBTree, with some supporting BTrees for collections of documents
to store element names, attribute names and text context. 

My work is immature and there are a host of drawbacks, but it has:

  * readonly DOM support

  * beginnings of XML:DB API support

  * beginnings of a very fast XPath query engine. This is where my 
    main focus is, besides efficient storage of XML.

It's called forest and the CVS archive can be found here:

Again, it's pretty immature, but lots of time and thinking went into this.
