Peter Linss has already replied regarding the principal question of whether comments should be allowed at the start or end (rather than just "between tokens" as the spec currently says); but in case it's relevant, I'd have thought that each "C* S* C*" and (distinct) "C*" in that should be [ C S* ]* (i.e. in effect [ C | S ]* ) i.e. that S and C tokens can be freely mixed [except that a literal reading of the current text is that C can't be the first or last token] rather than only allowing one S* run in a given [ C | S ]* run. I base this on the "may occur anywhere between tokens" text in section 4.1.9 that Peter Linss quoted, and the fact that S is a token (per section 4.1.1) and S* is not, i.e. the C's can go anywhere within that S* sequence rather than just either side of that sequence. (Sorry for the rather late reply, I just happen to be looking at style attribute parsing at the moment.) pjrm.
