Section 3 says:

   The ability to convey problem-specific extensions allows more than
   one problem to be conveyed.  For example:

   HTTP/1.1 400 Bad Request
   Content-Type: application/problem+json
   Content-Language: en

   {
   "type": "https://example.net/validation-error",
   "title": "Your request parameters didn't validate.",
   "invalid-params": [ {
                         "name": "age",
                         "reason": "must be a positive integer"
                       },
                       {
                         "name": "color",
                         "reason": "must be 'green', 'red' or 'blue'"}
                     ]
   }

It should say:

   The ability to convey problem-specific extensions allows more than
   one problem to be conveyed.  For example:

   HTTP/1.1 400 Bad Request
   Content-Type: application/problem+json
   Content-Language: en

   {
   "type": "https://example.net/validation-error",
   "title": "Your request parameters didn't validate.",
   "invalid_params": [ {
                         "name": "age",
                         "reason": "must be a positive integer"
                       },
                       {
                         "name": "color",
                         "reason": "must be 'green', 'red' or 'blue'"}
                     ]
   }

Notes:

The "invalid-params" member in the example is named incorrectly. According to Section 4, it should contain an "_" rather than a "-" in its name:

> If such additional members are defined, their names SHOULD start with
> a letter (ALPHA, as per [RFC5234], Appendix B.1) and SHOULD consist
> of characters from ALPHA, DIGIT ([RFC5234], Appendix B.1), and "_"
> (so that it can be serialized in formats other than JSON), and they
> SHOULD be three characters or longer.
