Hi All,

Seeing all the productive discussions and positive vibe on the list I sat 
down and read the current Editors draft of SHACL [1]

One of the things that strike me is that I cannot have a simple constraint 
on a language tag.

e.g. I need rdfs:label with '@en' for my application.

I do see a example in the "Native Constraints" section [2] but that looks 
rather complex for my use case.
On the issue tracker I did find ISSUE-35 [3] which resolves in allowing 
constraints on the language tag.

I tried searching the mailing list archive but 'Language' is so ambiguous 
that it didn't help me answer this question from the archive. 

Why is the use case mentioned in Issue 35 not there any more, and why is 
there no simple way constraint on the language of a literal?
