Yep - this definitely causes problems. Insert a node that includes a namespace
and all subsequent nodes end up with a namespace inserted. So ... I think this
presents a bug:
<root>
<nodes without namespace/>
<new nodes work well/>
</root>
vs.
<root>
<nodes without namespace/>
<node with namespace/>
<new nodes automatically get spurious namespace/>
</root>
Hope that helps - not sure how best to fix or work around this at the moment
though.
Cheers
Mike
