So it is local to this document. It has no global meaning within Open Alliance, so some other working group could use the same value in the same location, and it has a totally different meaning.
Also, 'by this document' means any future changes need to be in this document. Except when they are in another document, and decide to reuse the value 0x0a because it is local to the document....
So it actually looks like 0x0a does not have much meaning.
So why return it?
Does Open Alliance have any sort of global registry of magic numbers which are unique across specifications? Maybe you want to add another register whos value is not defined by this document, but something with bigger scope?
