Yes, that's good enough.  But please change the wording to say that
this is the grammar with which the package was tested, not just that
it "can be downloaded" from that place.  That way, users will know
that if they use a different grammar for the same language, they might
be on their own.

Sorry, I don't understand: are you saying that the HEEx grammar
supports both modes?  I thought you need a separate grammar for
Elixir.  I also thought the Elixir files have different file-name
extensions than the HEEx files.  Was I mistaken?

Maybe.  Otherwise, if they have a lot in common, you'd need to
duplicate stuff or have a common file used by both.  Your call.
