validation raises a TypeError under Python 3

[lelit]

Line 199 of validate.py is not compatible with Python 3:

Python 3.4 raises the same error.

Thanks @lelit - are you able to share your RAML file by chance?

[lelit]

Sure, here a minimal RAML that exhibits the problem (inline, as GH did not allow me to attach it... let me know if that's a problem):

#%RAML 0.8

title: Test
baseUri: http://customer.example.com/

traits:
  - orderable:
      queryParameters:
        sort:
          description: |
            Order the collection by arbitrary field(s).

            The value must be a JSON array of dictionaries like
            [{"property": "fieldName", "direction": "dir"}]
            where "dir" may be either "ASC", or "DESC.
          example: |
            sort=<<example>>
  - filterable:
      queryParameters:
        filters:
          description: |
            Filter the collection with the specified constraints.

            The value must be a JSON array of dictionaries like
            [{"property": "fieldName", "operator": "op", "value": "someValue"}]
            where "operator" may be one of: =, ~, ~=, >=, >, <=, <, <>.
          example: |
            filters=<<example>>
  - pageable:
      queryParameters:
        start:
          description: Skip over a number of elements by specifying an offset value for the query
          type: integer

          example: start=20
          default: 0
        limit:
          description: Limit the number of elements on the response
          type: integer
          required: false
          example: limit=80
          default: null

/:
  get:
    description: Get a collection
    is:
      - orderable:
          example: "[{\"property\":\"description_en\",\"direction\":\"DESC\"}]"
      - filterable:
          example: "[{\"property\":\"description_en\",\"operator\":\"=\",\"value\": \"Dynamite\"}]"
      - pageable

Should be better now :) will include this in the v0.1.9 release (not for another week or two) but it's in master. Thanks so much!
