[tei-council] Should Roma be doing this?

[James Cummings]

Gosh, interesting. I think if there is a default value then it 
should be impossible to have a closed valList without that being 
included.  I don't think it should automatically include it...but 
simply raise an error when processing such an ODD.

But this is just a gut feeling,
