It doesn't quite have a name of its own.  "Character range '0'..'9'"
is a discrete_subtype_definition, but it would still be that without
the type name.  Going further, this form of
discrete_subtype_definition is a discrete_subtype_indication, which is
just a kind of subtype_indication, which is a type or subtype name
optionally followed by a constraint.  See 5.5(4), 3.6(6), 3.2.2(3).
Note the *optionally*: you can write a loop providing just a type
(subtype) name without the range constraint---see Bob's response for
an example.

Yes, but only discrete types (integer or enumeration).
