In general I would agree. But not in a URL, I think. If the semantics are clearly defined for that parameter, then there is no issues with confusing semantics. Even CSS has short-hand forms for defning e.g. padding and margin as 4-tuples. Also, parsing a single parameter seems to me easier than parsing a whole set and making sure they are all there and consistent. But that's just my initial reaction - happy for more arguments. Cheers, Silvia.
