xml-dev - Re: Questions on DCD

[Dean Roddey <roddey@us.ibm.com>]

"While I like this proposal and think there is a definite need for it, I would
rather see it as an addition to, rather than a replacement of, a simple data
type attribute.

This is not a technical issue, merely a usability one.  It has simply been my
experience that explaining what a function is to non-technical or moderately
technical people is very difficult; explaining what a data type is, is not.

Furthermore, I suspect that 80-90% of the data typing needs in a document can
be
met by a subset of the DCD data types. I am therefore reluctant to get rid of
such a simple method, especially since data type attributes would be easily
reusable outside of schema files:"

I think I agree with that. I saw the validation scheme more as a way to do
advance stuff and which could,
if built into a parser, provide a way to do validation for any blessed W3C
typing scheme as well (behind the
scenes by just putting in a function bundle for those types and making the
parser aware of the fact that these
special types have associated validation functions out there to use.)
