It does not recommend a specific format but informatively documents how 
these formats can be used. Again, I am not alluding to this particular 
spec as a specific technical template for Filter Effects; as such pointing
out to specific items MSE does or does not define is probably not very 
productive. MSE is only referred to as an *example* of a standard that 
does not take a normative dependency on a specific technology but document 
how it does integrate with various alternatives.

If recommend refers to its definition in RFC 2119, no.

If recommend refers to its definition in RFC 2119, no.

I believe the feature should allow for more than one language and such a
technical mechanism should be defined. (Though I do not have a proposal
at this time). The spec may also informatively document how such a 
mechanism can be used with any specific technology the WG deems worth
documenting.
