[dsdl-discuss] Re: Potential use cases for complex value validation from ebXML

Rick

>I am very suspicious of validation relying on third-party resources. It
seems
to mix layers incorrectly. If the schema is to be found in a third-part
repository,
then there is some other layer that should take care of fetching it and
handling
exceptions before we get to DSDL. Not clear on this one...

What about if we do it another way: what if we make it necessary for
permitted datatype values to be declared locally but provide a mechanism
that allows the values themselves to be validated at some separate point in
the lifecycle, e.g.

<validEntries>
  <permittedValue source="http...." date="...." value="KOR KO">KO</value>
....
</validEntries>

Just a thought.

Everyone:

Haven't had any feedback yet on the idea of using a really minimalist string
matching approach rather than formally defining sets of datatypes. Is this a
total non-starter?
