as pointed out by Werner, ma:isRelatedTo is clearly not meant to be
limited to point to media resources in the example of section 6, so that
constraint was a bug introduced in the RDF ontology.

(I'm excluding the option to rewrite section 6 now... :)

I'm attaching the new XML/RDF and TTL ontologies.

Note also that I therefore renamed ma:isRelatedTo to
ma:hasRelatedResource, in order to be consistent in our naming scheme.

This must be reflected in the correspondence table of section 7.

This may also have an impact on the example RDF files produced by
others. Apologies about that...

I already replied to Jean-Pierre about that (I disagreed). Is anyone
esle pushing that proposal?

However, the attached version follows Jean-Pierre's proposal to simplify
some of the domain/range constraints (e.g. frame size) to make the
ontology more flexible.
