Re: Choice of sub-element or character-data in an element

Damned, sorry my previous message got sent before I completed it.

Hello :)

>From what I understood you want something like this :

<?xml version="1.0"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified" attributeFormDefault="unqualified">

    <xsd:element name="elementB">
        <xsd:complexType>
            <xsd:simpleContent>
                <xsd:extension base="xsd:string">
                    <xsd:attribute name="name" type="xsd:string"
use="required" />
                </xsd:extension>
            </xsd:simpleContent>
        </xsd:complexType>
    </xsd:element>

    <xsd:element name="elementA">
        <xsd:complexType>
            <xsd:choice>

                <xsd:element name="elementB">
                    <xsd:complexType>
                        <xsd:sequence>
                            <xsd:element name="elementC" type="xsd:string"/>
                            <xsd:element name="elementD" type="xsd:string"/>
                        </xsd:sequence>
                    </xsd:complexType>
                </xsd:element>

                <xsd:element ref="elementB" />

            </xsd:choice>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>

does this help or you want something more specific ?
