Hi Reuven,
how are, finally, the DOM nodes beeing released in MSXML? Is there a
release method for the root element, a release method for each element
or even a global release function?

I'd think about writing a wrapper interface that provides
1. a reference to the document that can be released without actually
releasing the DOMDocument object behind it
2. a reference to the DOM tree
3. a sane strategy to release things (regarding my first question).
