As you may know, in XSD 1.1 the constraints on xs:all have been relaxed so 
you will actually be able to do:

  <xs:complexType>
    <xs:all>
      <xs:element name="a" maxOccurs="unbounded"/>
      <xs:element name="b" minOccurs="0" maxOccurs="unbounded"/>
      <xs:element name="c" minOccurs="0" maxOccurs="unbounded"/>
      <xs:element name="x" minOccurs="0" maxOccurs="unbounded"/>
    </xs:choice>
  </xs:complexType>

XSD1.1 hasn't been released yet, but it shows things are moving in a 
suitable direction.
