How do you identify the "signatures"

[Tim Philomeno]

When I add digital signatures to my for, these "signatures" show up in the
data tree...I have not been able to find a way to name them or otherwise
identifiy which one goes with which..

Is there a way to do so? If not, can I go into the xsl/xsf and change them?

I want to write code on the section change events to allow or not allow
signing based on role membership...

Thanks!
