There is some inconsistency:

WS-DAI: there is an example of a LanguageMap value, which is a made-up URI for GenericQuery.

WS-DAIR: there is an example of a LanguageMap value, which isn't a URI. 

WS-DAIX: an example of a LanguageMap value, which is the URI of one of the spec documents.

As such, we clearly need to change the example in WS-DAIR.  Perhaps in WS-DAI we should state that the URI MAY identify 
the standard version of a language that is supported.  Perhaps in WS-DAIX, we could state that the URI used MAY be that 
of a W3C Specification Document?
