It sounds like this is just a difference between "encoding" and the principles of thesaurus construction, and not a contradiction.  The principles of thesaurus construction, as described in ISO 2788 or BS 8723, describe how each concept can be constructed and related to other concepts in a thesaurus.  The thesaurus standards do not prescribe any "encoding" method for maintaining a thesaurus.

Thesaurus management systems are free to use whatever encoding makes sense to maintain the information about concepts and relationships as described in the thesaurus standards.  If it is beneficial to have a terms class for SKOS this does not contradict the thesaurus standards, unless you are also making an assertion that terms are equivalent to concepts.

>From what I have read on the list, it didn't sound like anyone was saying that a term was equivalent to a concept, which would contradict the thesaurus standards.  What seemed to be said was that it was convenient to have a deeper "encoding" structure to maintain information about concepts.

The impression that I got was that there is a many-to-one relationship between terms and concepts and it was important to attach properties to terms which the current SKOS "encoding" does not support.  So a new "encoding" was proposed to maintain additional information associated with terms.
