	[rfc-i] ABNF (RFC2234)
		While it might look like the comments in the ABNF ABNF following the "rulelist" and "c-nl" definition lines (and a few others not excerpted above) are related to those rules, in fact per the ABNF they are not (unless the following line begins with whitespace, which we can't readily discern because of indentation).
		There are other issues related to c-wsp placement in the ABNF ABNF; I plan to address some of those separately.
		However, it appears that there are definitely issues related to comments and continuation with the ABNF as specified.

		It is provided as a convenience and is otherwise separate from the meta Crocker and Overell Standards Track [Page 2] RFC 4234 ABNF October 2005 language defined in the body of this document, and separate from its formal status.
		ABNF permits this incremental definition through the construct: oldrule =/ additional-alternatives So that the rule set ruleset = alt1 / alt2 ruleset =/ alt3 ruleset =/ alt4 / alt5 is the same as specifying ruleset = alt1 / alt2 / alt3 / alt4 / alt5 3.4.

	Speech Recognition Grammar Specification Version 1.0
		Augmented BNF syntax (ABNF): this is a plain-text (non-XML) representation which is similar to traditional BNF grammar and to many existing BNF-like representations commonly used in the field of speech recognition including the JSpeech Grammar Format [JSGF] from which this specification is derived.
		ABNF comments may appear between the declarations in the ABNF header after the ABNF self-identifying header.
		Both the XML Form and ABNF Form permit the grammar header to optionally declare a single rule to be the root rule of the grammar.

	Solution for GCS ! ambiguity in ABNF
		The proposed change to the ABNF that fixes it has been closely reviewed by Dave, Chetan, and myself, so we plan to roll this change into the 06 draft unless anyone has an objection.
		It should be unambiguous that the latter is a relative persistent XRI subsegment.
		However the current ABNF does not enforce this rule, so a relative XRI starting with "!" is currently ambiguous.

	Re: ABNF Re: Troubles with UTF-8
		ABNF uses non-negative integers to represent characters - note that it explicitly doesn't specify a range (2nd sentence of section 2.3).
		RFC 4234 specifies the encoding of those integers into ASCII, and says that other encodings may be specified.
		There's an implicit (obvious) encoding of ABNF characters into Unicode, and as Misha pointed out the IRI spec uses it - technically maybe it needs to be spelled out somewhere.

	Re: I-D ACTION:draft-crocker-abnf-rfc2234bis-00.txt
		Technically, to correspond to that actual use, crlf (case-insensitive) should be replaced with LF in those places (while retaining the definition of CRLF in the core rules).
		To accommodate local end-of-line conventions including CR by ABNF parsers, it might be desirable to instead change crlf to ([CR]LF).
		One rule in the section 4 definition of ABNF causes serious ambiguities: rulelist = 1(rule / (c-wsp c-nl)) That permits comment-only lines which are part of the rulelist, but not affiliated with a specific rule.

	RE: [xri] Initial proposed XRI 1.1 ABNF and issues analysis
		According to the ABNF (if xri-sub-delims are both used in the xri-path-segment production and in the xri-pchar production), one could consider the sub-segments to be (1) a, b, and c, (2) a;b and c, or (3) a and b;c.
		First, I think we should be relatively strict in the authority part and restrict the segment delimiters to only those that are valid delimiters.
		My concern is that showing other delimeters in the authority part will imply to people reading the ABNF that those delimiters might have some sort of meaning.

		The full form is: *element where and are optional decimal values, indicating at least and at most occurrences of element.

	APG Version 1.0 Description
		I found an ABNF validator and several unanswered questions on bulletin boards asking about the availability of general ABNF parser generators, but I didn’t actually find an example of a tool to generate parsers directly from an ABNF grammar.
		The distinction is, in ABNF, that a rule defines sub-strings of the strings defined by the grammar.
		Whereas an AST is a representation of the entire language defined by a grammar, a parse tree is a representation of a specific string in the language.

		It offers the convenience of requiring only an ABNF grammar file as input and generates as output a complete C++ class which functions, without modification, as a language string acceptor and parse tree generator.
		In addition, it provides a set of empty callback functions, one for each rule name, which can be used to write in semantic actions of any kind, including syntactic predicates, semantic predicates, string translations and error reporting.
		Version 4.0 offers several enhancements, most notably, the use of a superset of the ABNF rule forming operations (SABNF) for added flexibility in building the language grammar.

		Security Considerations GSER, and therefore the ABNF encodings described in this document, do not necessarily enable the exact octet encoding of values of the TeletexString, VideotexString, GraphicString or GeneralString types to be reconstructed, so a transformation from DER to GSER and back to DER may not reproduce the original DER encoding.
