I can always wish. An attribute worth indexing, IMHO is "number of children elements" or even "contains any child element".

You would still need to tell MarkLogic on before hand what to look for that shouldn't be there (which as far as I know isn't possible, at least, I haven't heard of a cts:missing-element-query yet). Or otherwise it would have to derive all possible elements from a schema or so (that might not be available) and index the absence of all of them. I am certain that would create a lot more index then you will ever use.. ;-) Kind regards, Geert Drs. G.P.H.
