Hello,

No, it's not valid.  You are trying to restrict xsd:string and extend it (by
adding attributes) at the same time.  You need to do it in two steps:

> >   <xsd:complexType name = "ConnectionTypeType1">
> >     <xsd:simpleContent>
> >       <xsd:extension base = "xsd:string">
> >         <xsd:attribute name = "OtherValue" type = "xsd:string"/>
> >       </xsd:extension>
> >     </xsd:simpleContent>
> >   </xsd:complexType>

> >   <xsd:complexType name = "ConnectionTypeType">
> >     <xsd:simpleContent>
> >       <xsd:restriction base = "ConnectionTypeType1">
> >         <xsd:enumeration value = "MaterialMovement" />
> >         <xsd:enumeration value = "Other" />
> >       </xsd:restriction>
> >     </xsd:simpleContent>
> >   </xsd:complexType>

Hope that helps,
Priscilla
