GB-0002 for all four DCORs

[MURATA Makoto (FAMILY Given)]

Both Japan and UK mentioned the idea of replacing "the current Edition"
and "the latest Edition" by "the fifth or later Edition" in the proposed
rewording (see below) for the footenote for the 4th edition XML1.0,
although I am not sure if we agreed on this change.

> Implementers should be aware that a further correction of

> Edition will be necessary when the related Reference 
> Specifications to which this International Standard also 
> makes normative reference and which also depend upon 
> XML, such as XSLT, XML Namespaces and XML Base, 
> are all aligned with the latest Edition  


Cheers,
