I don't want to break the pace of development. geotagging is relatively
new, and still in improvement, so let wait a mature stage before to bug.

and XML are just plain text files. But I think a XMP library should be high
level respect XML (hiding some details). If you look at xmp parsing in dt,
you see that there is no clean interface (and it seems based/copied from an
example of exiv IIRC). Additionally dt now read the tree and write the
entire tree (in a less readable form), moving around all stuffs. Also if I
imported an image without display it (no also no attempt to retouch the
image), dt will rewrite the xmp. So I think a XMP library (which know
better the structure of a XMP than a plain XML) should also try to insert
and delete lines, not to rewrite all file. And possibly the library could
contain some more high level translation (not for dt), but e.g. to simplify
to create short script to do statistics, handling, etc.
I think that I I reach to write the library, dt could profit improving (and
hiding) the details of xmp handling, but also many small external tools
could be implemented easilier. OTOH it is not so essential to dt.
[BTW I';m stuck in reading the various standards (XMP, IPTC, etc., and to
find a good XML library that could also handle malicious xml code ]

For sure. let reduce the lock-in
