How can I verify that that a document is signed using a QES (eIDAS)?

Hello,

As the recipient of a digitally signed document I would like to not only verify the basic validity of the electronic signature used but also that it is a QES (Qualified Electronic Signature) as defined by the EU eIDAS policy.

I now I can change trust manager services in Acrobat to check against the LOTL (List of trusted lists).

But in situations where only a QES will do how do I know for sure that the signature I'm looking is a QES?

Thanks!

Cathal
