[mercury-users] What is meant by "non-variable type" ?

[Terrence Brannon]

in "Semantics of type quantifiers" it is stated:

 A non-variable type is considered more general than an existentially
 quantified type variable.

I was wondering what a "non-variable type" is... this terminology
confuses me and I don't believe it was introduced or defined prior to
this point in the manual.
