Subject substitutionGroups not supported?
Date Tue, 27 Jul 2004 21:19:59 GMT
Hi, I am having troubles with substitutionGroups. Here
are the excerpts from my schemas:

1. BaseSchema:
<xs:element name="RequestEnvelope">
    <xs:sequence minOccurs="0">
      <xs:element ref="Body"/>
<xs:element name="Body" abstract="true"/>

2. SpecificSchema:
<xs:element name="Body"
      <xs:element name="ID">
	   <xs:restriction base="xs:string">
	     <xs:maxLength value="150"/>

scomp works well, but the generated java classes do
not compile. Specifically:
1. Base schema generates interface:

public interface BodyDocument extends
org.apache.xmlbeans.XmlObject {
  org.apache.xmlbeans.XmlObject getBody();

2. But a more specific schema generates following
public interface BodyDocument extends
mypackage.baseRequest.BodyDocument {
mypackage.specificRequest.BodyDocument.Body getBody();

Since mypackage.specificRequest.getBody() returns a
different type than mypackage.baseRequest.getBody(),
the src code does not compile.

I can fix this by hand in the java src code by making 
mypackage.specificRequest.getBody() to return

But this gets even worse if the base element is of
type="xs:string" which gets translated into
java.lang.String and the more specific element is
<xs:restriction base="xs:string"><xs:enumeration ..>
In that case I can not trick mypackage.specificRequest
method to return String as enumeration translates into
the subclass of a org.apache.xmlbeans.XmlString - not
a subclass of java.lang.String.

Any ideas how to work with substitutionGroup(s) for
the global elements in a more specific schemas that
are derived from some generic schema?
