Folks, The ABNF specification is up for reclassification to Draft Standard. This raises some interesting questions about how such a specification can be shown to "interoperate". Whatever the view on resolving such questions, it must begin by documenting use of the features in ABNF for other specifications. Hence, this note is soliciting comments on use of ABNF features, as documented in the current Internet-Draft: draft-crocker-abnf-v3-00.txt Especially interesting are any features that might be considered unusual, obscure or non-normative in the current draft. d/ ---------- Dave Crocker <mailto:dave@tribalwise.com> TribalWise, Inc. <http://www.tribalwise.com> tel +1.408.246.8253; fax +1.408.850.1850
