The Vendor Specific element is used to carry information not defined in this standard within a single defined format, so that reserved element IDs are not usurped for nonstandard purposes and so that interoperability is more easily achieved in the presence of nonstandard information. The element requires that the first 3 or more octets of the Information field identify the entity that has defined the content of the particular Vendor Specific element.
