Dear Hans,

You can use the PDF Accessibility Checker for Testing (this might be even better than Acrobat):

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
