I use to see other validators / conformance checkers, and I usually see:
- Error: something with an huge problem, making the file unplayable
- Warning: be careful, it is valid but it may not be the expected thing, 
e.g. 9 players will play the file well and 1 player will not, even if 
the file is conform to specs in theory (i.e. maybe the spec was not 
clear enough)
- Info: information only, you may be interested.

as the OP, I would be afraid about a warning, and consider that the 
muxer creates files with potential issues (actually void elements are 
harmless).
I would use the word "info" in that case.
