Let me make something clear: The EBNF for the presentation syntax in BLD is NOT NORMATIVE. It is not normative because it is *horrible* and we could not get the working group to accept it. However, no one was willing to propose a better alternative (including Hassan), everyone just criticized it. "Not normative" means, to me, that the presentation syntax is not a sanctioned way to express and exchange rules in BLD. It is solely for the purposes of expressing the semantics. However, it is clear (and has always been) that people will benefit from having a reasonable presentation (non-XML) syntax to write BLD rules in, and equally clear that such a syntax would benefit from some tooling, as Hassan is proposing. So, I consider the matter of the presentation syntax serialization - the nuts&bolts of the syntax including delimiters, the actual characters used, so-called shortcuts, etc., to be a matter still open for discussion and I would simply *love* for someone to take the time to specify one that is usable and acceptable to the group. The APS is a great start along these lines. If done right, it could be included back into the spec as normative. -Chris Boley, Harold wrote: > Hi Hassan, > > In the 26 Aug telecon we only decided to create a page for the *abridged* syntax. > Cf.
