Hi Jim,
The simplest thing is to move all the keys and keyref in the element
that include your activity and prodCategory elements. In this way you
have the declarations in scope. Assuming all the elements must have an
unique elemID and the parent of activity and prodCategory is an element
named document then the following should define your keys and keyref:
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="document">
<xs:complexType>
<xs:sequence>
<xs:element ref="prodCategory" maxOccurs="unbounded"/>
<xs:element ref="activity" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:key name="prodCategory.PK">
<xs:selector xpath="prodCategory"/>
<xs:field xpath="catName"/>
</xs:key>
<xs:key name="activityID.PK">
<xs:selector xpath="activity"/>
<xs:field xpath="activityID"/>
</xs:key>
<xs:key name="prodElement.PK">
<xs:selector xpath="prodCategory/prodElement"/>
<xs:field xpath="elemID"/>
</xs:key>
<xs:keyref name="elemRef.FK" refer="prodElement.PK">
<xs:selector xpath="activity"/>
<xs:field xpath="elemRef"/>
</xs:keyref>
</xs:element>
<xs:element name="prodCategory" type="prodCategory"/>
<xs:complexType name="prodCategory">
<xs:sequence>
<xs:element name="catName" type="xs:string"/>
<xs:element ref="prodElement" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
<xs:element name="prodElement" type="prodElement"/>
<xs:complexType name="prodElement">
<xs:sequence>
<xs:element name="elemID" type="xs:int"/>
<xs:element name="elemName" type="xs:string"/>
<xs:element name="elemOrder" type="xs:int"/>
<xs:element name="elemQuantity" type="xs:int" default="1"/>
</xs:sequence>
</xs:complexType>
<xs:element name="activity" type="activity"/>
<xs:complexType name="activity">
<xs:sequence>
<xs:element name="activityID" type="xs:int"/>
<xs:element name="elemRef" type="xs:int"
maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:schema>
Hope that helps,
George
