Adding both restriction and attribute(s) to complexType

Question

To a simple element with type="xs:int" I would like to add both a restriction and a number of attributes. However, the only way I have seen it done is in a two-step approach:

Declare a named (global) type and put all the restrictions in the named type
Refer to the named type in the base of an <xs:extension> and add the attributes to the extension node.

It could be nice if I could avoid declaring a global named type as the schema is generated dynamically and it would be a lot cleaner to specify all restrictions locally. E.g. like this:

<xs:complexType>
  <xs:simpleContent>
    <xs:extension base="xs:int">
      <xs:minInclusive>2</xs:minInclusive>
      <xs:attribute name="myAttribute" type="xs:boolean" />
    </xs:extension>
  </xs:simpleContent>
</xs:complexType>

or in case of a string-type:

<xs:complexType>
  <xs:simpleContent>
    <xs:extension base="xs:string">
      <xs:enumeration Value="FOO" />
      <xs:enumeration Value="BAR" />
      <xs:enumeration Value="BAZ" />
      <xs:attribute name="myAttribute" type="xs:boolean" />
    </xs:extension>
  </xs:simpleContent>
</xs:complexType>

Unfortunately, it does not seem that a "combined" declaration like this is allowed.

Have to admit I'm still a bit confused about basis on which answers are accepted on SO :( — oiavorskyi, Apr 04 '11 at 10:58

I saw the post but didn't thought it matched my problem. Giving it a closer look, I can see that it actually does. Thanks! – someName Apr 04 '11 at 10:49

Unfortunately it's not possible to do it. The way you do it currently (with separate type) is the way to go. Such requests were raised before (though maybe not in SO).
