Subject: Reference Capability hasReference.
XSD draft 17 adds a "hasReference" query clause to the Reference Capability. However, this query clause allows only for search based on *exact match* to a specified <reference> element. If we want to support search for objects that refer to a specific object, we'd need to add another query clause that accepts just a <psoID> element. If we want to support search for objects that have any reference of a specific type (e.g., any User beneath a certain context with a "memberOfGroup" reference), we'd need to add another query clause that accepts just a "typeOfReference" attribute. This might look something like "hasTypeOfReference" (below). Another way to do this (that might be easier) would be to define a query clause type (or to change HasReferenceType) to contain the *individual parts* of a reference. This would be the most flexible, since you could use it for an exact match or for a match just based on "toPsoId" or "typeOfReference". This might look like: <complexType name="HasReferenceType"> <complexContent> <extension base="spml:QueryClauseType"> <sequence> <element name="toPsoID" type="spml:PSOIdentifierType" minOccurs="0" /> <element name="referenceData" type="spml:ExtensibleType" minOccurs="0" /> </sequence> <attribute name="typeOfReference" type="string" use="optional" > </extension> </complexContent> </complexType> <element name="hasReference" type="spmlref:HasReferenceType"/>
