50		4.2.2.1.2.				what does it mean by 'snmp' and 'http' in the type of "TransportType" ?
Based on my understanding, all the requests and responses may use one of either TCP or UDP.	erase 'http' and 'snmp' in the list of "TransportType"		

Discussion 
1.	TCP and UDP can be classified into transport protocol familiy. However, SNMP and HTTP are not a kind of transport protocol. 
2.	In case of SNMP, it is being called as “network management protocol” based on top of both TCP and UDP. (Refer RFC1157)
	--> This protocol uses a set of methods: GET, SET, and TRAP (GET_Request and GET_Response, SET_Request and SET_Response, and so on..)
--> It seems difficult to figure out how to use SNMP for sending/receiving the requests/responses defined in the chapter 5.
  	3. In case of HTTP, it is being used called an application-level protocol for distributed, collaborative, hypermedia information systems. (Refer RFC2616)
		--> This protocol uses a set of methods: GET, HEAD, PUT, and DELETE
		--> It seems difficult to apply this protocol to the under developing coexsitence protocol. 

 Proposed Text

- In the section 4.3.1., delete http, snmp, and "..." as an option of transport type.
