One comment on this.

I see the syntax has been extended. The extension has introduced an 
ambiguity:

          imei-specifier = "imei:" ( imeival / ext-imei )
                                           [ ";" sw-version-param ]
                                           [ ";" imei-version-param ]
          ext-imei = gsma-defined-nonempty-string ;GSMA defined
                                                  ;and IETF
                                                  ;consensus
                                                  ;required
...
          gsma-defined-nonempty-string = 1*gsma-urn-char
          gsma-urn-char  = ALPHA / DIGIT
                          / "-" / "." / "_" / "%"/":"/";"/"="

ext-imei may contain a semicolon, and then following that a semicolon 
may also be used to initiate parameters.

	Thanks,
	Paul
