This element can be used in two different contexts:

1. In the context of tsd:objectRef:

   Purpose	In the context of tsd:objectRef, tsd:accessPredicate specifies a simple access predicate to join another doctype via tsd:nodeRef with the value of the current node which can be used to define filter expressions. Exactly one tsd:accessPredicate element is needed per tsd:objectRef element.
   Parent element	tsd:objectRef
   Child elements	tsd:nodeRef, tsd:nodeParameter
   Attributes	operator
   Type	xs:complexType

   Attributes

   Name	Type	Description
   operator	xs:string	In the context of tsd:objectRef, the operator attribute allows the specification of an operator to apply in the context of the tsd:accessPredicate element. Valid values are: = != < > <= >=

   Example

   This example shows the use of the tsd:accessPredicate element in the context of the tsd:objectRef element. An object reference is set up using /CustomerNo as a key:

   <tsd:objectRef>
     <tsd:collectionRef>Customers</tsd:collectionRef>
     <tsd:accessPredicate operator = "=">
       <tsd:nodeRef>/Customer/CustomerNo</tsd:nodeRef>
     </tsd:accessPredicate>
   </tsd:objectRef>
   

2. In the context of tsd:subTreeSQL:

   Purpose	In the context of tsd:subTreeSQL, this element specifies parameters to be used to build a "where" clause in retrieval expressions.
   Parent element	tsd:subTreeSQL
   Child elements	tsd:nodeRef
   Attributes	None
   Type	xs:complexType (with mixed content).

   Example
