Having looked a bit more into this, I see that my earlier assessment is
probably wrong.

So I'll leave the dependency as-is for now.

To test whether the XML functionality in osmosis still works, you can
let osmosis convert an OSM PBF file to XML and vice versa. For test data
I suggest the Liechtenstein OSM data from GeoFabrik:

http://download.geofabrik.de/europe/liechtenstein.html

Convert the PBF to XML, and the XML to another PBF. Convert the new PBF
to another XML file and compare both PBF & OSM files:

osmosis -v 9 --read-pbf file=liechtenstein-latest.osm.pbf \
             --write-xml file=liechtenstein-latest.osm

osmosis -v 9 --read-xml file=liechtenstein-latest.osm \
             --write-xml file=liechtenstein-latest.osm.pbf2

osmosis -v 9 --read-pbf file=liechtenstein-latest.osm.pbf2 \
             --write-xml file=liechtenstein-latest.osm2

Kind Regards,
