[tei-council] xml:lang="eng"

[Martin Holmes]

Hi all,

I thought we'd come to the conclusion that two-letter lang codes should 
be used where they exist, and three-letter ones where they don't, but 
ST-infrastructure.xml has lots of examples of

xml:lang="eng"

Before I change this, I thought I should check whether I'm wrong about 
our conclusion, especially since James edited this file the other day, 
and might have left "eng" alone on purpose.

Cheers,
Martin
