Question about datatype

Hi All,

On www-forms@w3.org there is a discussion going on about the notion of a 
xml schema datatype [1]. Does the term datatype in XML Schema only cover 
a simple type or also a complex type with simple content? From the XML 
Schema Part 2 I read the definition of a datatype to be the validation 
criteria of textual content (and to some degree structural because of 
e.g. xsd:QName and xsd:ID), is that correct or how would *the* good 
explanation of this look like?

Best regards,
David

this is the start of the mail thread but the question I'm asking here 
arises at the and of the thread.
