Al,
just a minor point
>A 'conceptual scheme' or 'concept scheme' is defined here as: a set of
concepts, optionally including statements about semantic relationships

schemes, terminologies, glossaries and other types of controlled

should read, 'subject heading systems' (NOT schemes)

This comes from 'subject heading languages'  SHL
(a good source for these are "Principles underlying subject heading
languages" (Muenchen: KG Saur, 1999)
When applied SHLs  become 'systems' (e.g. LCSH system, RSWK system, RAMEAU
system, EMBM system,
SIPORBASE system etc.) and systems contain terms.
The expression 'scheme'  is usually used for languages with symbolic
representation and are not
normally used in relation to SHLs

Also, it seems to be pretty safe to consider 'taxonomy' as a type of
classification.
But if a link between the two needs to be explicit then "classification
(taxonomical) schemes"
The main question is whether SKOS implementors also see it as a same type of
vocabulary
is what needs to be decided...
See below a typical example of classification and a typical example of
taxonomy

Classification (copy/paste from a UDC database)

599 Mammalia. Mammals
599.1	Prototheria (Eplacentalia). Egg-laying mammals
599.11		Monotremata
599.111		Tachyglossidae: Echidnas (Spiny anteaters)
599.112		Ornithorhynchidae: Duck-billed platypus
599.2	Metatheria. Metatherian mammals


Taxonomy of animals (the first I found on the web
http://www-biol.paisley.ac.uk/biomedia/text/txt_mammal.htm

CLASS : Mammalia
	SUBCLASS : Prototheria
		Example : Triconodonta *, Monotremata
	SUBCLASS : Theria
		INFRACLASS : Trituberculata *
		INFRACLASS : Metatheria
			Example : Marsupialia
		INFRACLASS : Eutheria
