Re: "Expanding" an enumeration

1) You're right, it's not allowed.  You can only <redefine> a type
(simple or complex) with a definition which would be legal as a
definition of a new type, and the only definition of new simple types
in terms of old is by restriction.

2) If you define the PartnerType as an open enumeration (i.e. a union
of an enumeration and string, in that order) you can at least cover
all the cases, while still documenting preferred usage.
