Exactly. I'm using 0.10.0 and I use settings to make it synchronise tags to
files. But whatever I do I can't get a file to report the digiKam XMP
namespace, not even digiKam itself in the XMP tag.

I feel kind of deflated with that statement. To say that I am no longer
allowed to write tags to old files that were previously tagged in 0.9.x is
to say that those files are now static and not allowed to change just
because I installed better software. That seems wrong.

For export as well as import?
