Parameters

signatureItem: The Digital Signatures Sequence Item that corresponds to the Digital Signature to be removed from the Data Set. To remove all the Digital Signatures in the entire Data Set, set this parameter to null.

Remarks

Call this method to remove a single Digital Signature by specifying the corresponding Digital Signatures Sequence Item. The method will delete the specified item from the Data Set. The Message Authentication Code (MAC) Parameters Sequence Item that was referenced by the deleted Digital Signatures Sequence Item will also be deleted if it is not referenced by a Digital Signatures Sequence Item anymore.

Call this method to remove all the Digital Signatures that exist in the Data Set by passing null to the method. In this case, all the MAC Parameters Sequence (4FFE,0001) and the Digital Signatures Sequence (FFFA,FFFA) Data Elements that exist in the Data Set will be deleted.
