btw. from the thesaurus users point of view, allowing a concept to have
'depictions' is a good thing, as a depiction can be part of describing the
meaning of a concept.  

So I was intending that the upcoming SKOS Core guide will have examples of
how to use 'foaf:depiction' with a 'skos:Concept' as the subject of the
statement.  (Which obviously fits with a scenario in which 'foaf:depicts' is
used with a 'skos:Concept' as the object of the statement, as part of a
description of an image.)

N.B. the idea behind 'skos:prefSymbol' and 'skos:altSymbol' is that these
are used to point to *symbolic labels* for concepts ... which is a different
thing from *depictions* of concepts (because a symbolic label may not
necessarily depict the concept it represents).
