Answer 2

I believe that you want an array of strings:

type: string[]

Answer 3

What you have defined is an Array of Objects, where each object has a field "type" of type "string". The problem is in the following part.

items:
  properties: # This is the problem. You have defined "properties" in each item. RAML thinks that it is an object with property "type"
  type: string

So your RAML will accept this array: [{"type": "stringvalue"}] You have to remove the properties keyword under items. Or you can use the shorthand version that Aled mentioned in his answer (which is more readable too, but I am mentioning this as sometimes you may need to define complex objects in which case you will have to use the below one).

#%RAML 1.0 DataType

type: object
properties:
  test:
    type: array
    items:
      type: string # This means that type of each item is string
