Hi Art, All,

If there is no use case for accessing this information (I was after why
you would want to access this information because I think just saying it
might be interesting to do so isn't justification enough), then I think
my original proposal holds - make the signature files unavailable to the
widget at runtime. 

For clarification I was not suggesting that an API should be added to
the DigSig spec but rather that some of the information could be exposed
via an API defined in the APIs and Events spec. But I don't think this
is necessary or worth the additional specification effort.
