Thank you for the tip about lov.okfn.org. My search there for 
"RegisteredOrganization" also (in addition to your suggestion below 
concerning 
http://business.data.gov.uk/companies/def/terms/companyProfile) returned 
the property rov:hasRegisteredOrganization. This seems on the surface 
also to be a candidate for the predicate I'm looking for. Although I 
notice that the domain of that property is dcterms:Agent. I'm still 
trying to understand what this means in practice: Does that mean:

    A) I need to declare my:Thing as being a dcterms:Agent?, or
    B) my:object is inferred to be a dcterms:Agent by virtue of the fact
    that I have used my:object as the subject of a
    rov:hasRegisteredOrganization predicate?

In either case, does the introduction of the new entity dcterms:Agent 
have any side-effects that I should be aware of?

That certainly looks like a good candidate for modelling the 
relationship I have described. I'm not sure how to choose between

    rov:hasRegisteredOrganization, and
    http://business.data.gov.uk/companies/def/terms/companyProfile, (and
    <http://business.data.gov.uk/companies/def/terms/companyProfile>
    other suggestions made elsewhere in this thread).

Am I right that the use of the UK-specific predicate 
http://business.data.gov.uk/companies/def/terms/companyProfile is 
appropriate when I am linking to UK-specific data (in Companies House). 
Could it in fact be argued that it provides more information because it 
declares that one can expect to find UK-specific Companies House data in 
the object of this triple?

I don't think you have misunderstood the question.

Here is an example URI of an SSEInitiative: 
http://data.solidarityeconomics.org/id/experimental/test/co-ops-uk/R000168
There's content negotiation set up to obtain HTML, RDF/XML and Turtle, 
but in any case, the RDF/XML and Turtle are displayed in the HTML page.
