| draft-mengwong-spf.  Therefore, we ask for consideration of the 
| following proposal:
| 
| The ABNF in -protocol 3.4.1 is (mostly from a post by Wayne)
| 
|    version     = "spf2." ver-minor "/" ver-scope *( "," ver-scope )
|    ver-minor   = 1*DIGIT
|    ver-scope   = "pra" / "mailfrom" / name
|    name        = alpha *( alpha / digit / "-" / "_" / "." )
| 
| And the following stipulations:
| 
|  1) "mailfrom" checking will be defined in a new draft
|  2) multiple records are allowed
|  3) a scope (e.g. "pra") can only appear in one record of one type for 
| validity purposes
| 
| The question before the working group: assuming no technical errors 
| with the above, is there anybody who vehemently objects with this 
| proposal?
