Interesting!
I failed to see why one would want to sign a PDF/A document, because
there's no obligation for PDF/A compliant readers to be able to verify 
the signature.
But the note made it clear it's possible to sign a PDF/A document anyway.
Thanks!

All of the data generated in your IT infrastructure is seriously valuable.
Why? It contains a definitive record of application performance, security 
threats, fraudulent activity, and more. Splunk takes this data and makes 
sense of it. IT sense. And common sense.
