This is the most important objective of the profile. A TD Consumer satisfying the requirements of a profile should be able to process any TD also satisfying the profile and should be able to correctly interact with all affordances of the Thing such a TD describes.

Note: this implies that a profile has three parts:

1. Restrictions on TDs
2. Implementation requirements, constraints and behavioral assertions for Consumers
3. Implementation requirements, constraints and behavioral assertions on Things

Note: We don't want to prevent a TD to have forms for additional protocols, but these can be ignored by compliant consumers, and could be removed without affecting profile comformance and compatibility. This may be useful for consumers that support multiple profiles.
