It's currently disabled, but we could turn it back on.
See gnuradio-core/doc/Doxygen.in

    # If the GENERATE_XML tag is set to YES Doxygen will 
    # generate an XML file that captures the structure of 
    # the code including all documentation.

    GENERATE_XML           = NO

I think #2's problematic since the XML would always be out of date,
and might not match the version of GR that the user has installed.
However, if you want to generate the XML and store it somewhere on
gnuradio.org, we can arrange that.
