The recent deposit v0.7.0 changed a bit some implementation part.
In the current case, the xmlns namespace are now used correctly.
So the icinga-plugins repository should change a bit its xml to respect that.
This results in builds in error both in docker-dev and icinga-plugins [1] [2] [3]
(it's the same tests).
Note: To be clear, the deposit tests in themselves are fine and in adequation
with their implementations.
