Yes, sorry, I overlooked that one. Now changed.

Yes, it would be a pity if there were confusion, but I do think that 
this is a SKOS problem, because using the word "term" as equivalent to 
"concept" is very misleading. We have been struggling for some time to 
emphasise the distinction between these two things. Is the usage you 
quote officially recognised by the Dublin Core people too? Can you give 
a reference?

I don't think that there is sufficient distinction in the definitions 
you give for "thesaurus term" and "term" for the difference to be clear 
to the normal reader. I would assume that "thesaurus term" means "a term 
found in a thesaurus", and I don't think that that adds enough to be 
worth including.

For the moment I have changed this to:

... Concepts exist in the mind as abstract entities which are 
independent of the terms used to label them.

I don't think that this is sufficiently distinct from "term" as defined 
above.

I know that this has s specialised meaning in SKOS work. If it is to be 
understood more generally, the definition you give would need to be 
expanded or clarified with examples.

I'll copy this to my colleagues Alan and Ron on the BSI working party, 
in case they have any views. Stella will get it anyway as she is on the 
SKOS list.
