Wayne,
Would it be possible to see what you submitted to Alan on this topic, before
it comes out in DLSW015?  I think this is a new CV for Version 1 so it might
be useful to see if we all agree on the description and syntax before it is
locked into the document.

Peter -

    Here is the text of what I submitted to Alan.  The Vendor Context CV is
    referenced in other places of the Capabilities Exchange section but
    there should not be any surprises.

7.5.11. Vendor Context (0x8B) Control Vector

   The Vendor Context control vector identifies the manufacturer's IEEE
   assigned Organizationally Unique Identifier (OUI) of the Data Link
   Switch sending the DLSw Capabilities Exchange.  The OUI is sent in
   non-canonical (Token-Ring) format.

   This control vector is optional and is used to provide the context
   for any Vendor Specific control vectors that follow in the
   Capabilities Exchange.  If there are multiple instances of the
   Vendor Context control vector, the specified context remains in
   effect for all Vendor Specific control vectors until the next Vendor
   Context control vector is encountered.
