RE: Schema definitions -- a discussion

["Ian Lowe" <ianlowe@xxxxxxxxxxxxxxxxx>]

Okay, reading this a bit more.. It sounds like we have a hybrid of XML/XSD
here.

XSD just seems to be W3C's version of a schema language - but it's
structure
would seem to do what we want. It seems though that an XSD is used for is
checking whether an XML document conforms to the schema, rather than the
general usage we are looking for.

There are VS tools (and I am guessing Java tools also) for handling XML and
extracting/setting values etc - are there similar tools for XSDs?

Then again... From wikipedia:

"An XML Schema Definition (XSD) is an instance of an XML schema
written in
the W3C's XML Schema language. An XSD defines a type of XML document in
terms of constraints upon what elements and attributes may appear, their
relationship to each other, what types of data may be in them, and other
things."

What's the relationship between the two then? And does the existance of XSD
mean we would still do the XML file, but provide an XSD to validate it?

Dang but that's a confusing lot of standards.

I.

I thought the XSD was a transformation that you did against an XML document
to "translate" it from one schema to another ?

Excuse me if I've got the wrong end of the stick, but isn't there
already a standard way in XML to describe schemas - the XSD?   We
wouldn't want to be reinventing the wheel if it can be avoided...
