DOOM class hierarchy is inconsistent with the Axiom interface hierarchy
-----------------------------------------------------------------------

                 Key: AXIOM-385
                 URL: https://issues.apache.org/jira/browse/AXIOM-385
             Project: Axiom
          Issue Type: Bug
          Components: DOOM
    Affects Versions: 1.2.12
            Reporter: Andreas Veithen


The OMDocument interface extends OMContainer, but not OMNode. On the other hand, \
DocumentImpl implements both OMDocument and OMNode (because it extends NodeImpl which \
implements OMNode).

That causes problems with code such as this (which is perfectly consistent with the \
Axiom API and which works correctly with the LLOM implementation):

if (item instanceof OMNode) {
    ...
    OMContainer parent = ((OMNode)item).getParent();
    ...
}
