Is there some free software that can verify if a given PDF file 
really is a valid PDF/A file?  If I want users to upload their 
documents to an archival webserver, I don't want them to upload 
bad files that aren't standards compliant and safe for the future. 

The web server needs to run a check, hopefully in less than a 
second and using predictable amounts of RAM.

Or how do you typically solve that problem?

Can PDF/A documents contain scanned images with OCR text?
