SYMPTOMS
Signature verification fails when you implement signed XML. This problem occurs when you use a custom ID attribute to identify the XML elements that you want to sign.



CAUSE
When you use this method to implement signed XML, unresolved XML Signature references occur. This problem occurs because the System.Security.Cryptography.Xml.SignedXml.GetIdElement virtual method is not called correctly.

STATUS
Microsoft has confirmed that this is a problem in the Microsoft products that are listed in the &quot;Applies to&quot; section.



MORE INFORMATION
To create signed XML, you must use the ID attribute to refer to the XML nodes. You may not be able to implement signed XML if your schema already uses an attribute that is named ID or if a program creates the XML and you cannot create ID tags.
