No.  The type definitions of most of the elements and attributes in
the W3C XML Schema namespace are defined with blockDefault='#all', meaning
that you cannot use anything other than the expected types for those

However there is a place where you are allowed to put your extensions,
namely the appInfo element:

<simpleType name="MyType" xmlns:my="http://www.example.org/Prasad/Extension";>
 <restriction base="string">
     <enumeration value="ABC">
           <my:Element value="xxx"/>
