I agree.

This is my experience to date, that, as you say, the requirements have to 
come from the standard itself (in this case, SPC-3). In other documents I 
have described that the 24-bit company_ID shall be obtained from the IEEE 
and that the meaning of the 48-bit number formed by appending a version 
number to the company_ID is the responsibility of the owner of the 
company_ID but---in accordance with IEEE tutorials on EUI-48---is expected 
to be unique in its usage to identify document(s).

With that in mind, how about:

"The VENDOR SPECIFIC EXTENSION ID, a 24-bit numeric value that is assigned 
by the organization associated with the IEEE company identifier, shall, 
within the scope of the IEEE COMPANY ID, uniquely identify document(s) that 
specify the supported software interface (see 
http://standards.ieee.org/regauth/oui/tutorials/EUI48.html for more 
information on EUI-48 usage)."

I'm open to other suggestions, too.
