[all] editorial review of section 1 of ITS sepc

Guys,
I just wanted to give a snap shot of where I am in reviewing section1, 
to get your feedback on some of the changes I'm proposing before i go 
much further, and also to make sure we don't unnecessarily duplicate 
editing work with the others doing editorial reviews (David, Aaron, 
Felix etc)

To date I've done some rework on 1.1, which i hope will then give us 
space to make 1.2 a bit more focused. The current 1.2 text is more a 
motivation for l10n and i18n rather than its per se, so this need to be 
refocussed onto more specific business-led interoperability problems.

I've inserted various MS word comment on what I think needs to be done 
on this and subsequent sections. Happy to hear any feedback, comments 
etc at this stage, and if anyone want to help with some of the 
subsection revisions that would be great.

I'll pick this up again on monday (I need to revise the provenance stuff 
today), so if you could send any input or feedback by then that would be 
helpful.

cheers,
Dave
