<br>
The DISPATCH chairs asked me to post here.<br>
<br>
My co-authors (Paul Kyzivat and Chris Newman) and I have created a few drafts to improve upon ABNF for IETF use. These are:<br>
<br>
draft-seantek-abnf-more-core-<wbr>rules-07<br>
Comprehensive Core Rules and References for ABNF<br>
***<br>
This document extends the base definition of ABNF (Augmented Backus-<br>
Naur Form) to include a reference syntax, along with core rules that<br>
provide comprehensive support for certain symbols related to ASCII.<br>
<br>
draft-seantek-constrained-abnf<br>
Constrained ABNF<br>
***<br>
This document extends the base definition of ABNF (Augmented Backus-<br>
Naur Form) to express a rule that is constrained by another rule. If<br>
a rule B is constrained by rule A, then every production generated by<br>
rule B must also be generated by rule A. By creating subordinate<br>
production forms, ABNF-using specifications can formally denote the<br>
relationship between a general rule and specific subsets of that<br>
rule, while preserving ABNF's context-free nature.<br>
<br>
draft-seantek-unicode-in-abnf-<wbr>02<br>
Unicode in ABNF<br>
***<br>
This experimental document adds support for Unicode strings in ABNF<br>
(Augmented Backus-Naur Form), and provides certain symbols related to<br>
Unicode code point ranges.<br>
<br>
<br>
These drafts are being discussed on abnf-discuss@, but since that is a fairly light mailing list, I would ask other participants to take a look and provide any feedback on these items. They are not ready for DISPATCHing yet, but we would like to keep them moving.<br>
<br>
Regards,<br>
<br>
Sean<br>
