[tei-council] new attribute @rational on num - ID: 2673045

[Gabriel Bodard]

I like Peter's solution of @value/@valueType (as I just noted in SF); 
it's more elegant that my suggestion, and at least *some* irrational 
numbers can be expressed in cdata (pi, for example). If it is not 
feasible to implement this in RNG--and would mean, for example, not 
controlling the content of @value at all--then, obviously, I vote _yes_ 
for the addition of @rational.
