Michael,

I've followed your suggestion and fixed the typo -- it was an oversight on my 
side instead. Note, though, that this operation is only executed once
per the stylesheet, and as you said, the only thing node-set() does is to
flip a bit.

The execution time didn't change at all, and it should not change.
