The IESG has no problem with the publication of 'Using Self-Delimiting
Numeric Values in Protocols' <draft-irtf-dtnrg-sdnv-08.txt> as an
Informational RFC.

The IESG would also like the IRSG to review the comments in

Technical Summary

   Self-Delimiting Numeric Values (SDNVs) have recently been introduced
   as a field type in proposed Delay-Tolerant Networking protocols.
   SDNVs encode an arbitrary-length non-negative integer or arbitrary-
   length bit-string with minimum overhead.  They are intended to
   provide protocol flexibility without sacrificing economy, and to
   assist in future-proofing protocols under development.  This document
   describes formats and algorithms for SDNV encoding and decoding,
   along with notes on implementation and usage.  This document is a
   product of the Delay Tolerant Networking Research Group and has been
   reviewed by that group.  No objections to its publication as an RFC
   were raised.
