don't forget you can always use alternatives at the Element.value point 
in an archetype - it's perfectly legitimate, e.g.

ELEMENT matches {
     value matches {
         DV_COUNT matches {.....}
         DV_CODED_TEXT matches {...}

this means that the data has to match a DV_COUNT or a DV_CODED_TEXT, 
which greatly reduces the possible unknown instance space you query against.
