Sure.

OK, I did not know that tag existed.

"Tagged PDF contains information about the structure of the document 
contents. This can help to display the document on devices with 
different screens, and when using screen reader software. " 
(<http://help.libreoffice.org/Common/Export_as_PDF#Tagged_PDF>)

Exporting an inaccessible document as "tagged PDF" may give people 
the impression that a document is accessible when they do only a 
superficial check (e.g. Adobe Reader's so-called accessibility check 
only checks whether the PDF is tagged or not).
I would also want to avoid that authors get the false idea that 
checking "tagged PDF" is all they need to do to produced accessible 
PDF. (Although I doubt that changing the default setting will make a 
difference to this type of authors.)

Best regards,

Christophe
