The relevant text now appears to be in section 4.6 Strings: A string <https://infra.spec.whatwg.org/#string> A is an ASCII = case-insensitive <https://infra.spec.whatwg.org/#ascii-case-insensitive> = match for a string <https://infra.spec.whatwg.org/#string> B, if the = ASCII lowercase <https://infra.spec.whatwg.org/#ascii-lowercase> of A is = the ASCII lowercase <https://infra.spec.whatwg.org/#ascii-lowercase> of = B. It would probably have been wiser to copy the normative definition into = the F&O spec, and add a note saying it was equivalent to something in = HTML. (A lot of people are still using XSLT 1.0, which defines format-number() = with a normative reference to JDK 1.1 documentation, which is no longer = obtainable on the web, as far as I can tell. We've become very = undisciplined - all this important stuff should be deposited on paper = copies in bricks-and-mortar libraries).
