Is it possible to define a new construct (i.e. like "element",
"attribute" ...) using XSchema that extends one of the old constructs? 

>From what i've been able to determine, this is done in the XSchema
definition itself in the following way:

<xs:complexType name="element" abstract="true" mixed="false">
    <xs:extension base="xs:annotated">
so it would seem that "element" extends "annotated". However if i try to
extend "element" in an external .xsd file - using a similar style as
<xs:complexType name="myElement" abstract="true" mixed="false">
    <xs:extension base="xs:element">

the validator always stops me with an "xs:element is an invalid value for
the extension base". 

your help is appreciated.
