XQuery implementation for registries which have relational tables

[Brian Thomas]

       Hi,

        I thought I would mention that we wrote some code a while back to beable
        to wrap relational databases with XML document, and hence, enable XQuery
        searches which descend into the relational tables, and return back as a proper
        XML document. Because the data are largely still held within the relational tables,
        the search is sped up (in theory) over execution over just a XML document.

        This should make it much easier to have both ADQL and XQuery support within 
        the registries.

        The code is checked into the NVO CVS site if people are interested:
