Title: Implement the field exists check.

This is an implementation of the field exists check. This enables one of the parts of ComplianceTest.test_four.
I intend to go on and implement another part of test_four that uses a regular expression match /SVG/.test(@.label)

Please advise if this doesn't match your way of doing things I will happily revise.
