This is the hash key of the attributes which make up the composite key--- InvoiceFormId and AgencyId ---for the Invoice Forms resource and used to uniquely identify an instance of Invoice Forms. The client should not generate the hash key value. Instead, the client should query on the Invoice Forms collection resource with a filter on the primary key values in order to navigate to a specific instance of Invoice Forms.
For example: publicSectorInvoiceForms?q=InvoiceFormId=<value1>;AgencyId=<value2>
