Shepherd writeup

This and its companion document passed ICNRG Last call in January, and has the support of the RG to progress toward publication as an Informational RFC. The two documents have had a long gestation period, and the RG debated multiple times the general importance of name resolution services as a distinct set of capabilities for ICN networks, and exactly what the scope of those services ought to be for different ICN architectures, including CCNx and NDN. While there is no strong consensus on that issue, from the last call comments (only a few) and the sidebar discussions, the chairs assess that on balance these documents provide useful background and a valuable discussion of various tradeoffs and approaches to the subject.

During pre-IRSG review by the IRTF Chair, some questions and issues were raised on the Arch Considerations draft. The authors prepared an updated version addressing these comments and also did an editing pass with the help of the document shepherd  to improve the writing. 

We therefore believe this document is ready for IRSG Review and hopefully progression toward publication.
