I'm not sure what you mean with "implement the update problem"; if you
want to bypass the current bug, you might try to create a simple
document without namespace (<root/>), and add new nodes as children.
The language you're using, or API, doesn't matter (as mentioned
before, you'll have most freedom with our own API).

I apologize for being slow here. Suppose I have a Atom feed XML document. I need to replace one entry. The entry contains XML from multiple namespaces.  I tried using the XQuery below:

declare namespace libx='http://libx.org/xml/libx2';

declare namespace atom='http://www.w3.org/2005/Atom';

declare variable $entry as xs:anyAtomicType external;

declare variable $id    as xs:string external;

declare variable $feed  as xs:anyAtomicType := doc('libx2_feed')/atom:feed;

delete node $feed/atom:entry[atom:id=$id],

insert node $entry into $feed

I ran it via the XQJ binding, setting $entry to a DOM node implementation.

This fails.

What do you suggest I do instead? If I want this to work, should I not be using XQuery?  Should I not be using a standard DOM node (using the built-in JDK org.w3c's implementation)?  Should I not be using XQJ?

I don't understand what creating a new document <root /> would do to address this problem. Also, it seems to me that replacing a part of a XML document (which is what I'm trying to do) should be a straightforward operation for an XML database.
