Exactly-- it seems that a tag library could work, or the DTD declaration
in the XML instance--namespaces and/or all--could be read by a search
engine to know what sorts of search options are available--e.g., via
pull-down options, etc.--as long as the DTD is public/system identified.

Is this viable?
