Valid type expressions

#1

The RAML 1.0 spec includes type expressions, but doesn’t really given a formal syntax for expressions.

I’d like to know whether something like this is consider legal (if a little overkill on syntax):

( string )

In particular, I think the array types in the following definition are equivalent:

types:
    Name:
        type: string
        minLength: 1

    Names_0:
        type: array
        items: Name
    Names_1:
        type: array
        items:
            type: Name
    Names_2:
        type: array
        items:
            type: ( Name )
    Names_3:
        type: ( Name )[]
    Names_4:
        type: Name[]
    Names_5: Name[]
    Names_6: ( Name )[]
    Names_7: ( Name[] )

Am I understanding the spec’s intention correctly?
