Is it possible to reference query parameter to enum defined in `definitions` ?

[unoexperto]

Is it possible to reference query parameter to enum defined in definitions ? For example consider following example:

paths:
 /users/test:
 get:
 summary: Test endpoint
 parameters:
 - name: osType
 in: query
 description: Client's OS type.
 required: true
 type: string
 enum:
 - ios
 - android

then I define this

definitions:
 OsTypes:
 type: string
 enum:
 - ios
 - android

Can I reference it from endpoint to avoid defining allowed values of the enum in every endpoint that uses it ?

I tried

schema:
 $ref: '#/definitions/OsTypes'

Thanks!

There's currently no way to reference definitions that are not body parameters. We're definitely considering changing that in a future version, which is covered by #301.
