RE: Time Stamp: tsa field in TSTInfo

[Robert Zuccherato <robert.zuccherato@xxxxxxxxxxx>]

Actually, I believe that when using CMS only the content (in this case
TSTInfo) is signed along with any authenticated attributes.  Thus, the
distinguishing information for the TSA would not be signed if it was not
included within the TSTInfo structure.
