6.3.2  SD-ID

   IANA controls ALL SD-IDs without a hyphen ('-') in the second
   character position.  SD-IDs are case-sensitive and uniquely identify
   the type and purpose of the SD-ELEMENT.  Experimental or vendor-
   specific SD-ID MUST start with "x-".  Anything that doesn't is
   managed by IANA.  The same SD-ID MUST NOT exist more than once in a
   message.
----------------------------------------------

To my understanding a vendor-defined SD-ID can not conflict with a
standardize one. 

BTW, i find 6.3.2 quite unclear. Firstly we say that IANA controls all SD-ID
without a - in second position.

	IANA controlled:
		plop
		foo-bar
		42

	(probably) Not IANA controlled:
		z-yyyy
		a-b-c

Then we add "Anything that doesn't is managed by IANA.". So, finally,
"z-yyyy" and "a-b-c" are controlled by IANA...

Confusing isn't it ?

Theses two sentences are not contradictory; the second one defines a larger
set of SD-ID.

Am I wrong ?

**** Response Alex
Clement,
thanks for clarifying.  The "hypen" part of the specification escaped me.
Yes, I agree the wording needs to be clarified.  Specifically, what is it
that IANA controls - everything without a hyphen in the second character
position, or anything that doesn't start with "x-"?  I would think the
second one is too restrictive.  That is, everything with hyphen in the
second position is proprietary, everything that is not, is not.  If you want
to reserve further characters such as "x" for experimental purposes, then so
be it, but not ALL characters except one should be reserved.  Otherwise,
this may result in a a tendency of proprietary SD IDs to get longer than
otherwise necessary, and there is probably value in keeping things compact.
