[tei-council] comments on edw90

[Christian Wittern]

Thanks for your comments Lou.  It looks like we are actually moving
forward a lot:-)

I can't claim to understand everything, but it looks good as you
present it.  Just some very small quibbles:

I assume what this comes down to is that every element in need of it
will get a @type directly without the indirection through the class system.

Does this mean that we deviate from the principle to base our stuff on
W3C datatypes?  Or does this mean that we get at them through rng:data?

That is very nice, but do you actually plan to provide the necessary
schematrons to do the validation?

Is this something different from xml:lang?  If yes, why do we need it?


All the best,
