I have a situation where I manage with both QWAC and QSEAL Certificates in my application but the only problem I have is when I try to differentiate them in order to check if the header where the QSEAL is provided is really a QSEAL cert and otherwise. I can't seem to find much info on the specifications and the metadata both of this certificates carry. Is there a unique identifier (OID or sth else) that all of the QSEAL or QWAC certificates carry which singles them out.

Thanks!
