I know how to create a pdf/a file with wpPDf, but how can i check if an existing file is pdf/a compliant with wpViewPdf?
How to detect if the file is a valid pdf/a?

Sorry, WPViewPDF does not check for PDF/A.
There are PDF validating programs out there which check certain markers and the syntax of the embedded XML. I do not know a tool which actually checks if the markers make any sense, i.e. if the document is accessible and if the embedded fonts are valid.
