RE: [xml-dev] Does a XSD schema define the minimum or maximum structure of an XML doc?

That would mean:

If the XSD schema designer does NOT insert xs:any or xs:anyAttribute
tags then (=default) additional 

attributes are NOT allowed
elements are NOT allowed

when the XML should be valid?

Is this your statement?
