[dsdl-discuss] Relax NG, datatypes, EBNF and other related topics

Hi,

I have been very impressed (and I still am) by the way James has used
Relax NG to specify the EBNF for the compact syntax.

Of course, it's not a valid RNG schema since it includes things such as
("grammar", "{", grammarContent*, "}") which violate the restrictions of
chapter 7, but I have always thought that some of these restrictions are
artificial ;-) and that's showing that a subset of the syntax of Relax
NG can be used to define EBNF grammars.

OTH, we are still struggling with the need for a formal language to
define the lexical space of datatypes (it's not the only issue with
simple types, but it's one of them) and I am wondering if there isn't
something to explore in this area: what about using an EBNF expressed
with Relax NG to define the lexical space of our datatypes?

Eric

Don't you think all these XML schema languages should work together?
