the relevant xsd pasted below. i'm unable understand actual error is. error on third line end. please help.

<xs:group name="prodvar">   <xs:all>      <xs:element name="prodvar" minoccurs="0" maxoccurs="1">         <xs:complextype>            <xs:sequence>               <xs:element name="varname" type="xs:string" minoccurs="0" maxoccurs="unbounded" />               <xs:element ref="skulist" />               <xs:element name="vstory" type="xs:string" minoccurs="0" />               <xs:element ref="attlist" />            </xs:sequence>         </xs:complextype>      </xs:element>      <xs:element name="colorswatchlist" minoccurs="0" maxoccurs="1">         <xs:complextype>            <xs:sequence minoccurs="1" maxoccurs="unbounded">               <xs:element name="colorswatch" minoccurs="0" maxoccurs="unbounded">                  <xs:complextype>                     <xs:sequence>                        <xs:element name="swatchname" type="xs:string" minoccurs="0" />                        <xs:element name="swatchheight" type="xs:string" minoccurs="0" />                        <xs:element name="swatchwidth" type="xs:string" minoccurs="0" />                        <xs:element name="colorname" type="xs:string" minoccurs="0" />                        <xs:element name="mainimageheight" type="xs:string" minoccurs="0" />                        <xs:element name="mainimagewidth" type="xs:string" minoccurs="0" />                        <xs:element name="mainimagename" type="xs:string" minoccurs="0" />                     </xs:sequence>                  </xs:complextype>               </xs:element>            </xs:sequence>         </xs:complextype>      </xs:element>   </xs:all> </xs:group>  <!--lot of other stuff -->  <xs:element name="prodvarlist" minoccurs="0" maxoccurs="1">     <xs:complextype> <!-- error here -->         <xs:group ref="prodvar" minoccurs="0" maxoccurs="unbounded" />     </xs:complextype> </xs:element>

just rid of maxoccurs="unbounded" in <xs:group ref="prodvar" minoccurs="0" maxoccurs="unbounded" />

in xsd 1.0, xs:all cannot repeat (here indirectly, may 'nice try!'), nor particle under xs:all, nor can nested under other compositor.
