Bill Mitchell updated AXIS2C-675:
---------------------------------

    Attachment: diff.txt

The attached diff.txt implements a change to attach all the namespaces in scope on an element node being detached to the element, so that the detached node and all its children will still have valid namespace references even if the former parent tree is freed.  

Beyond the obvious change to detach to preserve the namespace, it required cleaning up several places in om_element that would allow an attribute to be attached without the namespace structure it pointed to being declared at the element or one of its parents.  The former code seemed to accept that the namespace uri or prefix was declared somewhere, without requiring that the very same structure be used.  Testing also revealed another anomaly.  Now that guththila behaves like libxml and parses xml:id attributes, with this change the xml: namespace would be preserved in the detached node.  When that structure was subsequently serialized and passed to a remote system not using Axis, in particular a system using the Microsoft xml parser, this unnecessary but allowed xml namespace declaration is diagnosed as an error.  So we should just not emit it on output.

> When detaching a node from a parent, if the current node or any of it's children have any namespaces declared in it's parent or above, when the node is detached, and the parent freed, any namespace references are lost.
