The value parameter was another one that has to appear in between the piece definitions, and thus has to be ignored in unselected sets. I have done that now. I guess counterStrike=N also has a special meaning when it follows a piece definition, N then indicating a counter-strike group that piece should be added to rather than the number of a piece that is subject to the counter-strike rule. But this is a bit of an outlandish option, so I will leave that for now.
