RE: [relax-ng-comment] Non-XML Syntax question

[Michael Fitzgerald <mike@wyeast.net>]

The comma is a sequence operator -- read "and". The parens contain a group.
So, what the syntax is saying is this:

zero or more decl(s) can contain either a pattern or (|) annotations
followed directly by a grammar

hope that helps

Mike

Hi all,

The first BNF production for the Non-XML syntax (latest version) reads:

    topLevel ::= decl* (pattern | (annotations, grammar) )

Can anybody please direct me to the syntax for the particular BNF being used
here, as I don't understand what the "," comma operator is meant to signify.
e.g. How
does the above production differ from

    topLevel ::= decl* (pattern | annotations grammar )

?

many tias,

gary
