EUI-48 protocol ID for new VPD page 0x84

* From the T10 Reflector (t10 at, posted by:

The statement:

  "The VENDOR SPECIFIC EXTENSION ID, a 24-bit numeric value
  that is assigned by the organization associated with the
  IEEE company identifier, shall be unique within the scope
  of the IEEE COMPANY ID as required by the IEEE definition
  of EUI-48."

has problems from the word "shall" to the end of the sentence
since there is no normative reference provided for EUI-48.
As far as I can tell, if there are to be any standards
based requirements state here, they will have to come
|from SPC-3 because there is no other standard to reference.

The proposal as written leaves the glossary definitions,
acronym entries, and bibliography references for IEEE
Company ID and EUI-48 up to the discretion of the editor.
I do not mind these omissions, but will take a dim view
of complains about the results.

Thank you for considering these issues.
