Or we can create a rule which only allows x,y,z type for directive N, maybe that's better, because the input can differ (typos etc.)

Hello :) I looked at the existing rules when making the pr on docs. The attribute was spotted as non existent so i guess job was done, wasn't ?

No I am thinking about a rule where the project can define allowed code-block directive types.

Symfony would allow: php-attributes php-standalone yaml

Etc.

The referenced PR would then fail with sth like:

"Type "attribute" is not allowed for code-block directive. Allowed ones are: ......"

I hope it's more clear now
