returnfields need full xpath support
the current implementation of xpath used in metacat for the purpose of returning specific fields of an xml document within a returnset is not sufficient for highly structured documents. more or full xpath support needs to be implemented. currently, if you specify "/x/y" as a return field and the document is structured
metacat will return nothing. metacat seems to require that you specify the exact xpath to a node or it just returns null. This really doesn't work for any document that contains formatting (such as <p>, <i>, <b>, etc) within the xml.

after discussing this in the 1.9 triage meeting, it was decided that this will not be implemented. Returning ALL the leaves under a given node could be dangerous, and the client will likely not know how to deal with variable/extra returnfields given in the resultset document.
