At this point I want to emphasize that I'm not trying to troll you. I just happen to use Lezer and to dig into the obscure parts of the web platform. This litany of issues is the collateral damage of this unfortunate confluence. My apologies. About the bug in question, attribute selectors can have namespaces, and none of the following is parsed correctly:

[namespace|attr=val] { color: red }
[*|attr] { color: yellow }
[|attr] { color: green }

I will try to stop dumpster diving in CSS specs this week so you can put out a new release if you have the time. Thank you for all your hard work 🙃

Glad to hear you're not trolling me. It is apparent that my casual use of CSS has not prepared me for all the subtleties of the grammar (and the specs are, due to being fragmented into modules and levels, not the most helpful). I'm happy to find out about missing syntax, so don't worry about the issue spam.
