API blueprint MSON to define valid Attribute values?

Consider this excerpt from https://github.com/apiaryio/mson#example-1 ...

Example 1

A simple object structure and its associated JSON expression.

MSON

- id: 1 - name: A green door - price: 12.50 - tags: home, green

---

Let's say I would like to define valid values for the name attribute. Consider a context of API testing with a tool such as Dredd. We may need to define what are the expected/valid name values in response to GET'ing this resource, or else something is probably broken and this test step should fail.

And/or, if creating/updating a resource of this type, we may need to define what name values are valid/accepted. Is this currently possible to define in MSON?
(I believe this can be done in a JSON schema, which makes me hopeful for MSON support.)

Following is an example API Blueprint resource to illustrate how this would be used...

# Thing ID [/api/thing/id]

# List Thing ID attributes [GET]

    + Response 200

    + Attributes
        + href (string)
        + make (string)
        + model (string)
        + version (string)

    + Body

            {"href":"/api/thing/id","make":"BrandX","model":"SuperThingy","version":"10.1"}

In the above example, there are 3 known/accepted/valid values for the model attribute: CoolThingy, AwesomeThingy, and MLGThingy

Can we represent this resource in MSON, such that...

• Apiary (or other rendered) API documentation consumers can easily know what model values to expect?
• Dredd processes and passes/fails the model value in the response to a GET to this resource?

In MSON you can use enum, see the example below.

• name (enum[string])
  • joe (default)
  • ben
  • mark
