The mathematical English is the specification of the presentation
syntax. The BNF is only for illustrative purposes.

What is the "abridged syntax"?  Does it include abbreviation features
for IRIs, such as prefixes and relative IRIs? Does it include strings?
Does it include integers?
The last call working drafts of BLD and RDF+OWL both refer to DTB for
the specification of these "shortcuts".

I think we should be careful to move around this specification.

Why would you want a predicate for that? You can extract the language
tag and check equality. See also [1]

Shouldn't the language tag be a string specified by a specific RFC or
its successor?

You can test string-length=0
