On the last conference call I was tasked with sending you a sentence
describing a general "extensibility" capability within the protocol. Try
this ... Feel free to tweak.
"Support for additional service options characterized by scenarios like
Verify and TimeStamp should be provided for more generally as part of an
overall "extensibility framework". As such the introduction of various
options or directives on core DSS service operations can be extended to
support profile-specific requirements. This "extensibility framework" should
be designed to support the notion of compound or stacked operations typified
by the Verify and TimeStamp scenario as well as the more common notions of
"selection of response elements" or "specification of signing attributes".
