Hi Brad,
You are reviewing an old version of the LRM.
I made some comments below.

An object is an instance of a class. The class does indeed become a
user-defined type.
Many authors like to refer to a class as an encapsulation of
data and the subroutines that operate on that data. Here it is
being referred to as a collection of data and a set of subroutines
that operate on that data. I think they saying pretty much the same
thing. The word encapsulation might be a bit better though.

I don't see this in draft 2.

Actually a discussion on memory management is required. If you want
to know how to use classes effectively you need to know some specifics
about the "garbage collection" mechanism. Parts of this section could
problably be deleted but there definitely does need to be a discussion
on this topic in the LRM.
