Re: Schema Help

Title: Message

Hi Benson,   Most of the schema error messages issued by Xerces have a "code" just before the message. If you take that and append it to the XML Schema Part1: Structures URL as a fragment identifier you will get the relevant part of the specification corresponding with that error. In your case you get: http://www.w3.org/TR/xmlschema-1/#cos-nonambig   This means that a content model allows the selection of more that one particle for a given element as input. In general this kind of problems are solved by factoring the common part.   In your case the model is equivalent with:  <xsd:complexType name="ExtendedDataElementType">   <xsd:sequence>     <xsd:any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>   </xsd:sequence>  </xsd:complexType> To derive a more constrained model one has to have more details about your actual needs.   Hope that helps,  George ------------------------------------------------------- George Cristian Bina mailto:[EMAIL PROTECTED] <oXygen/> XML Editor - http://www.oxygenxml.com/ ----- Original Message ----- From: Benson Cheng To: [EMAIL PROTECTED] Sent: Thursday, January 08, 2004 8:03 PM Subject: Schema Help One of the complexTypes in my schema as below:    <xsd:complexType name="ExtendedDataElementType">   <xsd:sequence>    <xsd:choice>     <xsd:element maxOccurs="unbounded" minOccurs="0" name="values">      <xsd:simpleType>       <xsd:restriction base="xsd:string">        <xsd:maxLength value="1024"/>       </xsd:restriction>      </xsd:simpleType>     </xsd:element>     <xsd:element maxOccurs="1" minOccurs="0" name="hexValue" type="xsd:hexBinary"/>     <xsd:any namespace="##any" minOccurs="0" maxOccurs="unbounded"/>    </xsd:choice>    <xsd:element maxOccurs="unbounded" minOccurs="0" name="children" type="cbe:ExtendedDataElementType"/>   </xsd:sequence>  </xsd:complexType>   When I use Xerces (2.4.0) to validate a xml against the schema with the "schema full checking" on, and getting the following error:   [Error] test.xsd:522:50: cos-nonambig: "http://someNameSpace":values and WC[##any] (or elements from their substitution group) violate "Unique Particle Attribution". I think the complex type is not valid, but I don't know what's wrong, can someone help me how this complex type should be?   Thanks, Benson.
