I think that <AttributeDesignator> and 
<AttributeSelector> elements with mustBePresent attribute will 
cover
all cases:
 
<xs:complexType 
name="AttributeDesignatorType">
    <xs:attribute 
name="AttributeId" type="xs:anyURI" use="required"/>
    <xs:attribute name="DataType" 
type="xs:QName" use="required"/>
    <xs:attribute 
name="MustBePresent" type="xs:boolean" use="required"/>    
<-- new attribute
    <xs:attribute name="Issuer" 
type="xs:anyURI" use="optional"/>
</xs:complexType>
 
<xs:complexType 
name="AttributeSelectorType">
    <xs:attribute 
name="RequestContextPath" type="xs:string" use="required"/>
    <xs:attribute name="DataType" 
type="xs:QName" use="required"/>
    <xs:attribute 
name="MustBePresent" type="xs:boolean" use="required"/> <-- new 
attribute
</xs:complexType>
