Strong types in Axis2 wsdl

[Pugalia, Jai P (JP)]

Hi,
 
I have an Axis2 wsdl which exposes an ObjectType as 
 
<xs:element minOccurs="0" name="objectType" nillable="true"
type="xs:string"/>
 
I want to restrict the valid values to say "Array" and "Structure". If I
change the element to be an enumeration, it does not work as looks like
Axis2 does not support enumerations yet. Is there any other way I can
make this strongly typed in the wsdl.
 
Thanks,
Jai
