Your first example isn't correct from a formal definition pov, but can 
automatically be fixed up to be valid. The parser JOSM uses has two 
modes strict and non-strict, in strict mode it will complain about the 
construct as you would expect, in non-strict mode it will remain silent.

The 2nd example is clearly valid and osmose should not be indicating 
that as an error (osmose is now on it's 2nd parser implementation and 
I'm surprised that it gets so super basic stuff wrong).
