StructuralConstraint Complex Type Complex Type

Defines the elements used to create the structure of a constraint. The StructuralConstraint complex type contains the base constraint elements from which all structural constraints derive.

<xs:complexType name="StructuralConstraint">
    <xs:sequence>
        <xs:element name="Description"
            type="Description"
            minOccurs="0"
         />
        <xs:element name="DesignData"
            type="DesignData"
            minOccurs="0"
         />
    </xs:sequence>
    <xs:attribute name="Name"
        type="SimpleName"
        use="required"
     />
    <xs:attribute name="Evaluate"
        type="ConstraintEvaluation"
        use="optional"
     />
    <xs:attribute name="RaiseError"
        type="boolean"
        use="optional"
     />
    <xs:attribute name="ReturnEarly"
        type="boolean"
        use="optional"
     />
</xs:complexType>

Child Elements

Element	Type	Description
Description	Description	Description of the constraint.
DesignData	DesignData	Design-specific information about this constraint.

Attributes

Name	Type	Description
Evaluate	ConstraintEvaluation	Time to evaluate the constraint. The default value is Design.
Name	SimpleName	Name of this constraint.
RaiseError	boolean	true if a message should be returned to the user when this constraint fails; otherwise, false. The default is true.
ReturnEarly	boolean	true if the constraint evaluation can be terminated when the constraint is known to fail or succeed; otherwise, false. The default is false. Note  If you set the ReturnEarly attribute to true, you may speed up evaluation of the constraint; however, you may also fail to see some of the failure cases.
