Subject: xsd:choice using Xerces 2.0.0 (beta4)


This might be a silly question, but I'm having a problem validating against
an xsd:choice and I just can't see what is wrong.

The incoming XML looks like this:

<?xml version="1.0"?>
        <XMLMSG>
                <HEADER>
                        <SENDERAPPL>SONYNET</SENDERAPPL>
                        <SENDERUSR>*NA*</SENDERUSR>
                        <RECIPIENTAPPL>SONYNET</RECIPIENTAPPL>
                        <RECIPIENTUSR>*NA*</RECIPIENTUSR>
                        <MSG>ABO</MSG>
                        <PROCESS>GCPEATTRProcessTestConnexionEAI</PROCESS>
                        <PROCESSID>2194</PROCESSID>
                </HEADER>
                <BODY/>
        </XMLMSG>

and I am trying to validate against a schema that matches HEADER against
this:

        <xsd:complexType name="Header">
                <xsd:choice>
                        <xsd:group   ref="stdmessage" />
                        <xsd:group   ref="ackFromEAI"  />
                </xsd:choice>
        </xsd:complexType>

where the two groups are:

        <xsd:group name="stdmessage">
                <xsd:sequence>
                        <xsd:element name="SENDERAPPL"    type="mandatory" />
                        <xsd:element name="SENDERUSR"     type="xsd:string" 
minOccurs="0" />
                        <xsd:element name="RECIPIENTAPPL" type="mandatory" />
                        <xsd:element name="RECIPIENTUSR"  type="xsd:string" 
minOccurs="0" />
                        <xsd:element name="MSG"           type="message"/>
                        <xsd:element name="PROCESS"       type="mandatory" />
                        <xsd:element name="PROCESSID"     
type="xsd:positiveInteger" />
                        <xsd:element name="ACTID"         
type="xsd:positiveInteger" />
                </xsd:sequence>
        </xsd:group>
        <xsd:group name="ackFromEAI">
                <xsd:sequence>
                        <xsd:element name="SENDERAPPL"    type="mandatory"  />
                        <xsd:element name="SENDERUSR"     type="xsd:string" />
                        <xsd:element name="RECIPIENTAPPL" type="mandatory"  />
                        <xsd:element name="RECIPIENTUSR"  type="xsd:string" />
                        <xsd:element name="MSG"           type="ackMessage" />
                        <xsd:element name="PROCESS"       type="mandatory"  />
                        <xsd:element name="PROCESSID"     
type="xsd:positiveInteger" />
                </xsd:sequence>
        </xsd:group>

The incoming XML does not have an ACTID and should match against the
"ackFromEAI" group. Instead, I get a validation error. However, if I remove
the "stdmessage" group from the xsd:choice, it works fine.

Am I misunderstanding how this should work?
