Hi Andy,

You can have a first any of a, b, c any number of times and then follow 
them optionally with d followed by any of a, b, c, e, f any number of times:

<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema">
     <xsd:element name="element">
         <xsd:complexType>
             <xsd:sequence>
                 <xsd:choice maxOccurs="unbounded" minOccurs="0">
                     <xsd:element ref="a"/>
                     <xsd:element ref="b"/>
                     <xsd:element ref="c"/>
                 </xsd:choice>
                 <xsd:sequence minOccurs="0">
                     <xsd:element ref="d"/>
                     <xsd:choice maxOccurs="unbounded" minOccurs="0">
                         <xsd:element ref="a"/>
                         <xsd:element ref="b"/>
                         <xsd:element ref="c"/>
                         <xsd:element ref="e"/>
                         <xsd:element ref="f"/>
                     </xsd:choice>
                 </xsd:sequence>
             </xsd:sequence>
         </xsd:complexType>
     </xsd:element>
     <xsd:element name="a"/>
     <xsd:element name="b"/>
     <xsd:element name="c"/>
     <xsd:element name="d"/>
     <xsd:element name="e"/>
     <xsd:element name="f"/>
</xsd:schema>
