Hi,
I have an element called "grad_student" which extends "student". Now I want to extend "grad_address" element too since "grad_student" element needs address related info. Unfortunately I cannot merge address info from "grad_address" element into "grad_student" element. I am wondering how I can
extend another element when this element already extends a base element?
regards,
<xsd:complexType name="grad_student">
<xsd:complexContent>
<xsd:extension base="student">
<xsd:attribute name="name" type="xsd:string" use="required"/>
<xsd:attribute name="grade" type="xsd:string" use="required"/>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
<xsd:element name="grad_student" type="xyz:grad_student"/>
<xsd:complexType name="grad_address">
<xsd:complexContent>
<xsd:extension base="address">
<xsd:attribute name="state" type="xsd:string" use="required"/>
<xsd:attribute name="zip_code" type="xsd:string" use="required"/>
</xsd:extension>
</xsd:complexContent>
</xsd:complexType>
<xsd:element name="grad_address" type="xyz:grad_address"/>
