I'll want to add to the documentation on composite types, then. We'll need a
stern warning to users not to abuse them. Easily done, I think.

Composite types are frequently abused by OO and Windows programmers to break
the relational model. I used to be an MSDN member (thank you, I've
recovered) and frequently ran into, on the mailing list, users getting
themselves into some unresolvable mess becuase they'd used composite types in
SQL server to combine several rows ... or even effectively an entire child
table ... into one field.

Othewise, looks good to me. I don't think I'm qualified to second-guess you
on the implementation.
