I think you are :-)

To quote the attribute architecture document at
http://lcweb.loc.gov/z3950/agency/attrarch/attrarch.html

	Functional Qualifier Attribute Type
	[...]
	The Semantic Qualifier and Functional Qualifer types
	correspond to "type" and "role" respectively.  The Semantic
	Qualifier describes the term itself, while the Functional
	Qualifier describes the relationship of the term to the object
	being searched. For example, consider a search on an author,
	where the author is a person and thus the term is a personal
	name. The Access Point attribute value would be 'name', the
	Semantic Qualifier value would be 'personal name' and the
	Functional Qualifier value would be 'author'.

So the FQ isn't just telling you that the name Victor Davies is that
of a composer, but that it has the _role_ of composer with respect to
the records you're trying to find.

Hope that clears things up.
