Re: [csswg-drafts] [selectors-4] Clarify :lang() behavior when the language range is not a well-formed BCP 47 code (#8720)

Thanks all for the valuable discussion. It seems that much work remains to be done, in multiple places. I therefore propose:

- in Selectors 4, to delete the text

> Language ranges that are not well-formed language tags or which would not be a well-formed language tag if an initial wildcard character "*" were replaced with a valid subtag, do not match anything.

- to re-tag this issue for Selectors 5
