Hi Simon,

You may be thinking of the non-normative OWL DL sub-set [1]:

    C.3. SKOS RDF Schema - OWL 1 DL Sub-set (informative)

    For the convenience of tools and applications that wish to
    work within the constraints of OWL DL, the SKOS RDF Schema -
    OWL 1 DL Sub-set [SKOS-RDF-OWL1-DL] provides a modified,
    informative, schema which conforms to those constraints.
    Note that this schema is obtained through the deletion of
    triples representing axioms that violate OWL DL constraints.
    Alternative prunings could be performed.

    The SKOS OWL 1 DL Sub-set is available by citing its URI:
    http://www.w3.org/TR/skos-reference/skos-owl1-dl.rdf
