Hello,

annotations can apparently be stored in two ways, either as an xml
file in .kde/share/apps/okular/docdata or as an export into a document
archive.  While it is simple to go from the former to the latter, I
did not find way to go back.  In fact it would be nice if it were
possible to save the annotations explicitely in an xml file anywhere
in the directory without the main pdf document.

Best regards,

Josef.
