7. Conformance

Contents of DED 0.1

Class	Requirement
Definition	Begins with the envelope of section 2, with a `ded` this document defines and the origin of a designer type.
Host	Recognises, checks and reads a definition as section 4 says, writes a new one as section 5 says, and never changes an envelope. It is the DESL host of DESL section 11.
Validator	Checks a definition's envelope against `ded.schema.json`, and its content against the file schema of its designer type when there is one.
