Problems with setContentAsDOM if the DOM uses namespaces

[Geoffrey Shuetrim]

I am using the setContentAsDOM method provided by XMLResource instances
to specify the content that I wish to insert into an Xindice database
but am running into problems if the DOM object that is provided as an
argument has had nodes created using the createElementNS or
setAttributeNS methods.

The attached source code provides two JUnit tests.  One works because it
does not have namespace declarations for the nodes in the document.  The
other fails because it does.  The tests assume that the database URI is:
xmldb:xindice://localhost:8180/db

The problem occurs at the point where the database manager attempts to
insert the XMLResource into the relevant collection, complaining about
difficulties parsing the document.

My environment is as follows:

OS: Debian testing
Container: tomcat 4
Xindice: 1.1b4

Any insights into what is going wrong would be very much appreciated.
