[xmlsec] Pin Caching

[Wouter]

It might depend on the way your signing key is selected. Now it is done 
via the template, and therefore probably each time reselected and 
reloaded from MS certificate store (and thus from your card), could you 
try to load the key inside the application itself and keep it during the 
three signatures? Does that make any difference?
