JBK:
As for the rule, since the head verb (aux) requires to select a LIGHT expression, I don't think we need to say the non-head to be [LIGHT +]. As you said, it is redundant.
Stefan: For German it is needed since the copula does not select LEX+. So the schema has to decide. Maybe.
The data suggests that the copula has to enter coherent constructions, but the LIGHT value of the copula is not defined (it cannot be since NPs and PPs are permitted as well) and the LIGHT value of the head cluster schema is not defined either. In the copula paper it was LEX+. But in the German Clause Structure book it is not defined.
