Need help in syntax of XML schema

Hi
I've created a xsd file in VS2005 as below.

<?xml version="1.0" encoding="utf-8"?>
<xs:schema id="ReportSetting" targetNamespace="http://PopularERP/ReportSetting" elementFormDefault="qualified" xmlns="http://PopularERP/ReportSetting" xmlns:mstns="http://PopularERP/ReportSetting" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msprop="urn:schemas-microsoft-com:xml-msprop" version="1.0">
  <xs:element name="ReportSetting">
    <xs:complexType>
      <xs:sequence>
        <xs:element name="Report" minOccurs="1">
          <xs:complexType>
            <xs:sequence>
              <xs:element name="Parameter" minOccurs="0" maxOccurs="20">
                <xs:complexType>
                  <xs:sequence />
                  <xs:attribute name="Name" type="xs:string" />
                  <xs:attribute name="Prompt" type="xs:string" use="optional" />
                  <xs:attribute name="ParameterValue" type="xs:string" msprop:nullValue="_empty" use="optional" />
                  <xs:attribute name="Visible" type="xs:boolean" default="true" />
                  <xs:attribute name="Type">
                    <xs:simpleType>
                      <xs:restriction base="xs:string">
                        <xs:enumeration value="String" />
                        <xs:enumeration value="Integer" />
                        <xs:enumeration value="Date" />
                        <xs:enumeration value="Boolean" />
                        <xs:enumeration value="Decimal" />
                        <xs:enumeration value="CorporationId" />
                        <xs:enumeration value="Item" />
                        <xs:enumeration value="DetailAccount" />
                        <xs:enumeration value="SummaryAccount" />
                      </xs:restriction>
                    </xs:simpleType>
                  </xs:attribute>
                </xs:complexType>
              </xs:element>
              <xs:element name="Description" type="xs:string" default="String.Empty" minOccurs="0" maxOccurs="1" />
            </xs:sequence>
            <xs:attribute name="Name" type="xs:string" />
            <xs:attribute name="PromptParameter" type="xs:boolean" />
            <xs:attribute name="Format">
              <xs:simpleType>
                <xs:restriction base="xs:string">
                  <xs:enumeration value="html" />
                  <xs:enumeration value="pdf" />
                  <xs:enumeration value="xls" />
                  <xs:enumeration value="tiff" />
                </xs:restriction>
              </xs:simpleType>
            </xs:attribute>
            <xs:attribute name="Title" type="xs:string" />
            <xs:attribute name="Folder" type="xs:string" />
            <xs:attribute name="ReportType">
              <xs:simpleType>
                <xs:restriction base="xs:string">
                  <xs:enumeration value="cs" />
                  <xs:enumeration value="rpx" />
                </xs:restriction>
              </xs:simpleType>
            </xs:attribute>
          </xs:complexType>
        </xs:element>
      </xs:sequence>
    </xs:complexType>
  </xs:element>
</xs:schema>

The problem is when I use the schema to create a new xml file as below, VS thought the xml has syntax error.
<?xml version="1.0" encoding="utf-8" ?>
<ReportSetting xmlns="http://PopularERP/ReportSetting">
  <Report Name="LOGI_02" Title="Inventory Value Report" Format="html"  PromptParameter="true" ReportType="cs" Folder="Inventory">
    <Description>Show total value of inventory as at a specific date.</Description>
    <Parameter Name="corporationId" Prompt="CorporationId" Type="CorporationId"   Visible="false"/>
    <Parameter Name="atEndOfDate" Prompt="As at end of" Type="Date" Visible="true" />
  </Report>
</ReportSetting>

When I add the first child under <Report>, the intellisense give me choices of <Description> and <Parameter>.  After adding <Description>, there is no choices for <Parameter> any more.  If I type the XML manually, the first <Parameter> is underlined saying "The element Report in namespace http://PopularERP/ReportSetting has invalid child element Parameter in namespace http://PopularERP/ReportSetting".
What I want to achieve is to have one or none <Description>  and none and multiple <Parameter> under <Report>.  Can you help me to correct my xsd if it is not defined properly?

Thanks
