RE: Genericity and XML-Schema

polymorphism xml

I think this will make you happy. The key here is to indicate the type of
list being used by using the xsi:type="blah" attribute in the instance:


<?xml version="1.0" encoding="UTF-8"?>


<complexType name="list.Type">
         <element name="item1" maxOccurs="unbounded" minOccurs="0"/>
         <element name="item2" maxOccurs="unbounded" minOccurs="0"/>

<complexType name="listEx.Type">
        <extension base="g:list.Type">
                <element name="item3" maxOccurs="unbounded" minOccurs="0"/>

<element name="list" type="g:list.Type"/>

<element name="lists">
            <element ref="g:list" maxOccurs="unbounded"/>


document instance:

<?xml version="1.0" encoding="UTF-8"?>
   	xsi:schemaLocation="http://www.example.org ../schemas/generic.xs"

    <g:list xsi:type="g:listEx.Type">
