Thanks. That's exactly what I would expect, based on the name "parameterized regex". I have used that approach many times.
Since my OP, the purveyor of the poorly chosen phrase has admitted the name was chosen in haste, and he may change it. Besides the normal clutter of imprecise language from native speakers, the primary developers on the software in question are not native speakers. I always try to give non-native speakers more slack. (But marketing types and others, whose job it is to find the right words, get the sharp edge of the dictionary.)
