Whether # there is a match is based solely on the identifier C being either equal to, # or a hyphen-separated substring of, the element's language value, in the # same way as if performed by the '|=' operator. The matching of C against the # element's language value is performed case-insensitively for characters # within the ASCII range. # # C must not be empty. Selectors3, 6.6.3 (The language pseudo-class :lang) [http://www.w3.org/TR/selectors/#lang-pseudo] says: # Whether an element is represented by a :lang() selector is based solely on # the element's language value (normalized to BCP 47 syntax if necessary) # being equal to the identifier C, or beginning with the identifier C # immediately followed by "-" (U+002D). The matching of C against the # element's language value is performed case-insensitively. [...] # # C must be a valid CSS identifier [CSS21] and must not be empty. (Otherwise, # the selector is invalid.) In particular, selectors3 introduces normalization, removes the (implied) restriction that characters outside the ASCII range are matched case-sensitively, and introduces the restrcition that C must be a valid CSS identifier. Should CSS21 be changed to match selectors3?
