Re: [dxwg] Profiles should contain constraint information

@nicholascar "If a profile is defined in a "guidance" form only, e.g. expressed as a PDF doc only, then requiring constraint information will mean it can't be expressed in this ontology."

To my mind, constraints do not have to be machine-actionable. The DCAT-AP includes cardinality and other constraints. To validate, a human would have to turn those stated constraints into some actionable code, but the constraints are still expressed in the AP. There is a plethora of metadata documentation in document form that is used (by humans) to create validation programs and "cross-walks" between metadata types. Although we should be moving into a more machine-actionable environment, our guidance document needs to include the current low-tech practices.

To whit, I see the guidance document having two threads:

1. The concept of profiles and the information they contain (including why the information is useful)
2. Some advice on practices that increase the utility and usability of profiles, like machine-readable vocabularies, presentation of validation schemas, etc.
