This Power PDF Advanced facility checks the compliance of PDF/A files you create or receive. To create such documents, use Save As in the File menu and choose PDF/A as the file type. Click Settings to choose the compliance level (see below).
PDF/A is a set of standards for PDF files, to ensure maximum accessibility over a wide range of PDF products under different platforms, and also to make the files 'future-proof'. PDF/A is based on PDF version 1.4, so older PDF products can handle them. It excludes elements like JavaScript which may not be correctly interpreted in some environments. It requires certain items, such as adequate tagging, good accessibility and suitable metadata.
