This might also help:

<xsd:complexType name="timeframeType">
	<xsd:choice>
		<xsd:group   ref="both"/>
		<xsd:group   ref="oneorother"/>
	</xsd:choice>
</xs:complexType>

<xsd:group name="both">
  <xsd:sequence>
    <xsd:element ref="earliestdate"/>
    <xsd:element ref="latestdate"/>
  </xsd:sequence>
</xsd:group>

<xsd:group name="oneorother">
  <xsd:choice>
    <xsd:element ref="earliestdate"/>
    <xsd:element ref="latestdate"/>
  </xsd:choice>
</xsd:group>

thanks,

Thank you.  That is just what I was looking for.  Based on that then the

following should work correct?

<xs:complexType name="timeframeType">
	<xs:choice>
		<xs:sequence>
			<xs:element ref="description"/>
			<xs:element ref="earliestdate" />
			<xs:element ref="latestdate" minOccurs="0"/>
		</xs:sequence>
		<xs:sequence>
			<xs:element ref="description"/>
			<xs:element ref="earliestdate" minOccurs="0" />
			<xs:element ref="latestdate" />
		</xs:sequence>
		<xs:element ref="earliestdate" />
		<xs:element ref="latestdate" />
	</xs:choice>
</xs:complexType>
