This is equivalent to

  ( (elem1, elem2?) | (elem2, elem1?) )

so

 <xs:choice>
  <xs:sequence>
   <xs:element ref="elem1"/>
   <xs:element ref="elem2" minOccurs="0"/>
  </xs:sequence>
  <xs:sequence>
   <xs:element ref="elem2"/>
   <xs:element ref="elem1" minOccurs="0"/>
  </xs:sequence>
 </xs:choice>
