Do you want to know how the CSS WG works? Fantasai has written about:csswg, An Inside View of the CSS Working Group at W3C.
Resolved: David Baron’s proposal accepted as editorially amended by fantasai.
Rationale:
Authors are used to CSS allowing spaces almost everywhere, and will most likely expect them to work here as well. Also calc() will either allow or require spaces, and :nth-child()‘s syntax should be consistent with that.
Resolved:: Copy attribute selector wording from Selectors into CSS2.1 to resolve incompatibility.
Resolved:: *=, ~=, ^=, $= all accept the empty string, but match nothing. Note that this overrides a previous resolution which stated that such attribute selectors are invalid.
Rationale:: These selectors are meaningless. This resolution matches existing implementations for ~=, which was introduced in CSS2.1, and makes *=, ^=, and $=, which were introduced in Level 3, consistent with that.
