Using key() returns all the field elements in the document that have a
key_fld of 'NeedCode'. Your expression that uses the predicate directly only
selects the field elements that are children of the context node. Without
knowing what the context node (or anything else in your source document)
looks like, one can't be sure that's the problem, but it seems likely.
