quick reply on that one:
Note that we still allow the lang tag outside the quotes as an 
abbreviation in the abbreviation section:

I understand you just mean this should be stated somewhere more 
explicitly, yes?

My personal opinion: because the length of lang-tags is not typically of 
concern, I'd assume... if you need it, you probably can emulate it with 
a regular expression using the pattern facet (depending on what regexp 
syntax is allowed here, didn't check in detail) or, in the RIF/XQuery 
built-ins version you could first extract the  lang tag and then use the 
respective string built-ins.

As for the other issues, I refer to my co-editors.
