In section 184.108.40.206 (#COBICOR), the Guidelines say:
The elements author, editor, and respStmt are the default members of the model.respLike class
I think "default" here means something like "basic", and so I propose revising to use that word.
(I find "default" to be a dangerous term in technical documentation in general and especially in the TEI Guidelines. After all, the members of model.respLike are all equal in the eyes of the ODDs.)
