Hi!

Would you consider an API to validate whether a particular input was valid under RFC 6570 (or does such a thing exist already and I've missed it)?

E.g., http://example.com/dictionary/{term:1}/{term is not a valid URI Template seemingly, but I cannot see an API that complains about that -- uritemplate.URITemplate will happily truncate the end part there and consider that a template with just one field.

(Even having URITemplate do enough validation of its inputs would also work).

Full context: JSON Schema Draft 6 adds a uri-template format. I'd love to use uritemplate to implement it in jsonschema.
