Subject: [xml-dev] xml schema extension

What are the rules for extending in XML schema from a base class but not
adding any additional attributes or elements. 

like say I have a bass class foo and I would like to have a foobar class
that extends foo.  I just want to extend it for description purposes and in
case in the future there is a need to add some attributes or elements to
this sub class. 

would this be all that I need to do?

<xs:complexType name="foobar">  		
		<xs:extension base="foo"/>
