Serialize A Selector ==================== "2. Otherwise, for each simple selector in the sequence of simple selectors that is not a universal selector of which the namespace prefix maps to the null namespace (not in a namespace) or of which the namespace prefix maps to a namespace that is not the default namespace serialize the simple selector and append the result to s." I have absolutely no idea what this is saying. Even if I did, the concatenation of clauses is ambiguous. This needs to be rewritten, possibly into multiple sentences, to be clearer. I'd suggest text, but as I said before, I don't know what it's trying to say. "3. If this is not the last part of the chain of the selector append a space (U+0020), followed by the combinator ">", "+", or "~" as appropriate, followed by another space (U+0020) if the combinator was not whitespace, to s." This implies that one must append >, +, or ~. A slight rewording would be good here. "If this is not the last part of the chain of the slector, append a space to s. If the combinator linking this part of the chain and the next is not the universal combinator, append a ">", "+", or "~" as appropriate, followed by another space (U+0020), to s." "4. If this is the last part of the chain of the selector and there is a pseudo-element, append "::" followed by the name of the pseudo-class, to s." should be "followed by the name of the pseudo-element". Serialize a Simple Selector =========================== "4. If this is a universal selector append "* (U+002A) to s. " Missing a " after the *. "4. If a is one or minus one and b is zero let the value be "n" (U+006E)." (This critique also applies to line #5.) :nth-child(-n) doesn't represent the same thing as :nth-child(n). Namely, the former represents *no* elements. I know that Selectors says otherwise. It directly contradicts itself slightly further down, when it says "The value a can be negative, but only...". The last example in the spec, :nth-child(-n+6), is explicitly given as representing something different from :nth-child(n+6).
