FYI here is an excerpt from another XML schema that defines an XML
Key, as well as a reference and unique constraints on those keys:

               <xs:key name="PEOPLE_PK">
                       <xs:selector
xpath="sis:Personnel_Roster/sis:Investigator/sis:Commons_Username"/>
                       <xs:field xpath="."/>
               </xs:key>
               <xs:keyref name="MENTOR_NOT_IN_ROSTER_FK"
refer="sis:PEOPLE_PK">
                       <xs:selector
xpath="sis:Personnel_Roster/*/sis:Mentor_Commons_Username"/>
                       <xs:field xpath="."/>
               </xs:keyref>
               < xs:keyref name="PI_NOT_IN_ROSTER_FK" refer="sis:PEOPLE_PK">
                       <xs:selector xpath="sis:Grant_Info"/>
                       <xs:field xpath="sis:PI_Commons_Username"/>
               </xs:keyref>
               <xs:unique name="PUBLICATION_NOT_UNIQ_UK">
                       <xs:selector
xpath="sis:Publications/sis:Publication"/>
                       <xs:field xpath="sis:PubMed_ID"/>
               </xs:unique>
               <xs:unique
name="COMMONS_USERNAME_NOT_UNIQ_IN_PERSONNEL_ROSTER">
                       <xs:selector
xpath="sis:Personnel_Roster/*/sis:Commons_Username"/>
                       <xs:field xpath="."/>
               </xs:unique>
