(I didn't mention existence in the above general statement, but this is just the condition $\omega|_N$ is closed, since any such form has a closed extension to a neighborhood of $N$.) However, the last statement really is more general, since it also covers non-constant rank embeddings - for example a generically symplectic embedding with a coisotropic locus. | |
