Extending enumerated simple content of complex types

As a corollary to my earlier question on successive restriction of simple
content in complex types:

In my xbrli namespace I have the following type:

 <complexType name="stringItemType">
  <simpleContent>
   <extension base="string">
    <attribute name="nonNumericContext" type="IDREF" use="required"/>
    <anyAttribute namespace="##other" processContents="lax"/>
   </extension>
  </simpleContent>
 </complexType>

I now define a new type in my dt namespace as follows:

 <complexType name="accountTypeItemType">
  <simpleContent>
   <restriction base="xbrli:stringItemType">
    <enumeration value="account"/>
    <enumeration value="bank"/>
    <enumeration value="employee"/>
    <enumeration value="customer"/>
   </restriction>
  </simpleContent>
 </complexType>


Suppose I now want to define another type in another namespace that has as
simpleContent the enumerations from dt:accountTypeItemType and, in addition:

    <enumeration value="job"/>
    <enumeration value="vendor"/>
    <enumeration value="fixed-asset"/>

What is the best way to do this? I would like the resulting type to derive
from xbrli:stringItemType but I want to have a modular system that doesn't
require me to re-enumerate the list from accountTypeItemType in my new type.
Is this even possible in XML Schema?

Thanks

Hugh
