Add error type details

[nichtich]

Should the format support inclusion of information about error types, in addition to it's identifier, e.g.

• local identifier
• URL for help
• message
• tags/levels/...
• ...?
• custom fields, e.g. pattern such as Constraify Analysis Result Format

How about an addition field typeDetails of a report/error with a JSON Object:

{
  "typeDetails": {
    "no-duplicated-names": {
      "message": "Names must not be duplictated", ...
    }
  }
}
