I think profileDesc comes under the charter clause :

Other Deliverables,,
Subject to its capacity, the working group may choose to develop additional
relevant vocabularies in response to community demand.

(unless it ends up being recast as a specialisation of the emerging
dcat:Resource generalised class)

Either way it:
  a) needs to be described as a vocabulary using W3C style
  b) be referenced as part of the guidance of DCAT profiles - which I think
SHOULD be described in relationship to other more general DCAT profiles
(and other profiled standards) using profileDesc

ProfileDesc is far simpler and more general than DCAT guidance - so its
going to be easist and most useful to publish it standalone then leverage
in the guidance doc.

I also think profileDesc can be used within the guidance doc as the example
formalism for describing best practices around profiles formally
identifying the nature and role of constraints definitions.

Overall the guidance doc should address all those requirements we can't
hard-code into DCAT, but will use need to use additional ontologies to
support.  For example, the issue of describing a constraint that a
particular reference vocabulary is used in content can be described using
RDF-Datcube, which can bind a data element to a set of skos:Concepts from a
given ConceptScheme.

ProfileDesc provides the vocabulary needed to discover and access
constraint sets and interoperability of specialised profiles with their
base profiles. At this stage no other candidate has been provided. (I have
reviewed ADMS and it doesnt seem to cover the conformance aspect, and seems
to be compatible with an alignment of prof:ImplementationResourceDescriptor
in the same subclass heirarchy as dcat:Distribution)
