> I cannot split this sub-TLV across two TLV 22 advertisements i.e.,

Hmm based on what Tony wrote I read it that you could actually split it as 
shown ... I think the draft could improve if the split boundaries were to be 
clearly defined.


[LES:] Egads!! The consequences of allowing that would be highly undesirable. 
It would change parsing logic to require multiple LSPs to correctly parse a 
single codepoint and require an indication of ordering i.e., which TLV is the 
first in a set, which is the second, etc.
No way!

V10 of the draft has been published with the additional language I mentioned 
earlier:

“Each TLV that is part of an MP-TLV MUST be parsable independent of
   other TLVs in the MP-TLV.  Breaking of a single sub-TLV or other data
   unit across TLVs MUST NOT be done.”
