Dear Hans,

You can use the PDF Accessibility Checker for Testing (this might be even
better than Acrobat):
http://www.access-for-all.ch/en/pdf-lab/pdf-accessibility-checker-pac.html

And to add to your motivation ;-) :
Google ranks tagged PDFs higher than non-tagged PDFs. For those moving from
MS Word to ConTeXt this is a must.

Thank you for all your effort!

Christoph
