    .Net XmlValidatingReader should fail on complextypes with whitespace?

    I believe the .Net XmlValidatingRe ader should fail when validating XML
    that contains a ComplexType element with white space when the
    ComplexType element has the mixed attribute set to false in the XSD used
    for validation.

    XSD fragment:

    <xs:element name="TRSellerB uyerData">
    <xs:complexTy pe mixed="false">
    <xs:sequence>
    <xs:element ref="BuyerSelle rReferrorFlag" minOccurs="0"
    maxOccurs="unbo unded"/>
    </xs:sequence>
    </xs:complexType>
    </xs:element>

    XML fragment:

    <TRSellerBuyerD ata>
    </TRSellerBuyerDa ta>

    XML Spy will catch the valdation error and report: "Text not allowed
    inside element 'TRSellerBuyerD ata'

    But the following code does not catch the validation error. Is this a
    bug in XmlValidatingRe ader - or am I missing code to catch this? I
    assume by XSD is correct since XmlSpy catches the error.


    XmlTextReader textReader = new XmlTextReader(r eader);

    textReader.Whit espaceHandling = WhitespaceHandl ing.All; //this is the
    default

    textReader.Norm alization = false; //this is the default

    XmlValidatingRe ader validatingReade r = new XmlValidatingRe ader(textReader );

    validatingReade r.ValidationTyp e = ValidationType. Schema;

    validatingReade r.Schemas.Add(s chemaCollection );

    try
    {
    while(validatin gReader.Read()) ;
    }
    catch(Exception ex)
    {
    Debug.WriteLine (ex.Message);
    }

      The following complexType's ContentType is ElementOnly according to
      structures spec. (http://www.w3.org/TR/xmlschema-1)
      and if the ContentType is ElementOnly, then whitespace characters are
      allowed according to clause 2.3 of the following rule in the spec:
      3.4.4 Complex Type Definition Validation Rules
      Validation Rule: Element Locally Valid (Complex Type)
      2.3 If the {content type} is element-only, then the element information item
      has no character information item [children] other than those whose
      [character code] is defined as a white space in [XML 1.0 (Second Edition)].

              Thank you Priya, how would I change my XSD so that only child elements
              are allowed and no "significan t" white space?
