The DNS has a large installed base and repertoire of protocol
  specifications. The DNSEXT WG group will actively advance DNS
  protocol-related RFCs on the standards track while thoroughly
  reviewing further proposed extensions. The scope of the DNSEXT WG is
  confined to the DNS protocol, particularly changes that affect DNS
  protocols "on the wire" or the internal processing of DNS data. DNS
  operations are out of scope for the WG.
  
  The WG will limit itself to review of proposals for new extensions
  and clarification to the DNS protocol, including DNSSEC. Adoption of
  new work targeted for standards track will require changes to this
  charter.
  
  The working group can nevertheless undertake work in following
  subjects without a charter change:
  	DNSSEC and TSIG/TKEY algorithm maintenance
  	Hardening DNS protocol and providing guidance to implementors
  	Advancing existing Proposed Standard RFCs to Draft/Full Standard
  	Obsoleting RFCs.
  	Maintaining a Wiki containing a guide to DNS protocol RFC's. 
  	Improving DNS zone synchronization mechanisms 
  	Examining transport protocols, possibly adding new ones.
  
  Before formal adoption of any such items at least 5 working group
  participants must publicly state that the item is within charter and is
  worthwhile item for further study.
  
  The DNSEXT WG will conduct the specified RFC5395 review of RR
  templates as they are posted, and EDNS0 Option templates if EDNS0-bis
  updates registration requirements.
  
  The WG will review DNS protocol related work which may originate
  elsewhere in the IETF, including AD-sponsored submissions or drafts
  in other working group. The WG does not intend to hold face to face
  meetings, though may do so if deemed necessary for resolution of a
  specific issue at hand.
