See Scott Cantor's answer.  xsd:integer is what schemas calls a "simple" 
type.  When used on an element, it allows no attributes, except for 
xsi:type itself, xsi:nil, maybe xsi:schemaLocation (I can't remember and 
don't have the spec here).  So, ID= is not valid on an element of any 
simple type.  You need something like:

 <xsd:complexType name="integerWithID">
   <xsd:simpleContent>
     <xsd:extension base="xsd:integer"> 
       <xsd:attribute name="ID" type="xsd:id" />
     </xsd:extension>
   </xsd:simpleContent>
 </xsd:complexType>

Again, I'm doing this from memory, so I may have some details in the above 
schema wrong.  You could also make the ID attribute optional.  It's an 
extension because it allows elements not allowed by integer itself (I.e. 
it allows the attribute too.)  Anything with attributes is by definition a 
complex type.  Integer is a simple type.

I must be dense.  Why?  Please use little words.
