RE: Schema definitions -- a discussion

["Ian Lowe" <ianlowe@xxxxxxxxxxxxxxxxx>]

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...
