Office 2013 and later

The XdSignatureRelation enumeration is used to determine how digital signatures can be added to a SignedDataBlockObject object.

Namespace:  Microsoft.Office.Interop.InfoPath.SemiTrust
Assembly:  Microsoft.Office.Interop.InfoPath.SemiTrust (in Microsoft.Office.Interop.InfoPath.SemiTrust.dll)

'Declaration
Public Enumeration XdSignatureRelation
'Usage
Dim instance As XdSignatureRelation

Member nameDescription
xdSignatureRelationSingleSpecifies that only one signature can exist in the SignedDataBlock.
xdSignatureRelationCoSignSpecifies that signatures are independent of each other in SignedDataBlock.
xdSignatureRelationCounterSignSpecifies that each signature signs the preceding signature in the SignedDataBlock.

These enumerated values are returned by the SignatureRelation property.
