Yes, I encountered that too.  Unfortunately they apparently didn't
implement the whole DOM API in DOOM, I think they only did what was
minimally necessary to get WS-Security stuff to work for Rampart via the
Apache xmlsec library.  :-(

Haven't looked at the new Axis2 1.4, but in 1.3 there are utility
methods in org.apache.axis2.util.XMLUtils that handle conversion both ways:

toOM(Element)
toDOM(OMElement).

They're expensive, however, as they essentially just serialize the input
representation into a byte array stream, and then re-parse and
re-unmarshall into the output representation.
