Nobody I can find lists two separate categories: both sentential and connective. There is a lot of overlap between sentential and connective clauses, the ones we looked at from section 4 onwards having the characteristics of both sentential and connective relative clauses.
And sometimes there is even overlap with standard non-defining realtive clauses modifying nouns.
