      Description

      Validation using the following xsd and xml results in two different results between XercesJ and XercesC++.
      For java I get the error reporting the sequence error right after the processing of element <url> because <name>
      cannot appear after <url>. But for C++ the error is not reported until the last element within <person> has been
      processed. This obviously isn't correct because by that time it is too late. The way Java is reporting it seems to
      be correct so that I can stop processing the xml file.

      <?xml version="1.0" encoding="UTF-8"?>
      <xs:schema xmlns:xs='http://www.w3.org/2001/XMLSchema'>
      <xs:element name="person">
      <xs:complexType>
      <xs:sequence>
      <xs:element name="name" type='xs:string' minOccurs='0' maxOccurs='1'/>
      <xs:element name="email" type='xs:string' minOccurs='0' maxOccurs='unbounded'/>
      <xs:element name="url" type='xs:string' minOccurs='0' maxOccurs='unbounded'/>
      <xs:element name="link" type='xs:string' minOccurs='0' maxOccurs='1'/>
      </xs:sequence>
      </xs:complexType>
      </xs:element>
      </xs:schema>

      <?xml version="1.0" encoding="UTF-8"?>
      <person xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
      xsi:noNamespaceSchemaLocation='foo.xsd'>
      <url>www.foo.com</url>
      <name>Boss</name>
      <email>chief@foo.com</email>
      <link/>
      </person>

      The output from running the XercesJ 2.9.1 Writer sample on the above xsd/xml is:

      <person xsi:noNamespaceSchemaLocation="foo.xsd">
      <url>www.foo.com</url>
      [Error] foo.xml:5:11: cvc-complex-type.2.4.a: Invalid content was found star
      ting with element 'name'. One of '

      {url, link}

      ' is expected.
      <name>Boss</name>
      <email>chief@foo.com</email>
      <link></link>
      </person>

      The output from running the XercesC++ 3.0.1

      <?xml version="1.0" encoding="LATIN1"?>
      <person xsi:noNamespaceSchemaLocation="foo.xsd">
      <url>www.foo.com</url>
      <name>Boss</name>
      <email>chief@foo.com</email>
      <link></link>

      Error at file C:\xerces-3_0_1\bin/foo.xml, line 8, char 10
      Message: element 'name' is not allowed for content model '((name,email,url),li
      nk)'
      </person>
