TElXMLCustomDecryptionTransform is a descendant of TElXMLTransform.
The following paragraph was taken from the W3C Recommendation
"Decryption Transform for XML Signature":
This transform supports two modes of operation. In XML mode the data is encrypted XML and the result of decryption is a node set. In binary mode the data is an encrypted octet sequence and the result of decryption is an octet sequence. In both modes,
the input node-set can be excluded from processing using
below via XML Schema [XML-Schema] and appears as
direct child elements of the
attribute value of the
elements within the input to the transform. The value MUST be a non-empty
same-document [URI] reference (i.e., a number sign '#'
character) followed by an XPointer expression [XPointer] as profiled by
Reference Processing Model [XML-Signature,
dcrpt:Exceptelement is represented by TElXMLDecryptionExcept.
