UK Comment 5

Patrick, all,

as suggested in UK's comment 5, I have replaced the referencne to the OASIS 
version of the Relax-NG specification with a reference to the ISO version:

[RNG] James Clark, MURATA Makoto, RELAX NG Specification, http://oasisopen.
org/committees/relax-ng/spec-20011203.html, OASIS, 2001.

now reads

[RNG]	ISO/IEC 19757-2 Document Schema Definition Language (DSDL) -- Part 2: 
Regular-grammar-based validation -- RELAX NG, 2003

Best regards

Michael
