[tei-council] Deleting an attribute from its class, but reinstating it on an element

[Lou Burnard]

If you delete it from the class, you can't then sneak it back in again. 
Deletion trumps all other specifications. Like my teeth, once they're 
gone, they're gone.

You have to define a completely new  attribute on <category> with an 
attDef mode="add". If it was an element, it would have to be in your 
namespace, but (as we discussed a few weeks ago) all TEI attributes are 
in the null namespace, so there;s nothing to stop you adding this one in 
to the same nonexistent place.

The reason <attRef> is not very well documented is that neither 
Sebastian nor I can ever remember what it's actually for.
