Re: A28: syntax of markup declarations? (LONG)



(Speaking only for myself)

I have thought about Tim Bray's proposal to use the same syntax for
instances and markup declarations and find that I am in complete
agreement.

1. It makes no sense to claim that we have created a syntax suitable
for the markup of structured data in general and then not use it for
the markup of the structured document that defines a particular
schema.  From a marketing standpoint this is indefensible; from a
logical standpoint it is absurd.  I have heard no one deny this.

2. I am not qualified to certify the correctness of the proposed DSD
syntax, but I can guarantee that it would be no harder to teach than
the current DTD syntax, and I strongly suspect that it would be
easier.

3. Unlike many other features -- marked sections, for example -- that
we can defer for the moment if we wish and introduce in a later
version of XML, this is not something that can wait.  We have to take
this approach from the beginning or it will never happen.

If there are flaws in the DSD syntax included in the November
draft, then early implementors will soon expose them, but if it's not
in that draft, we're stuck with an illogical and indefensible failure
to employ the very philosophy that we are espousing.

I think we should do it.
