abstract = {Some restrictions on the in- and out-degree of transitions
in Petri nets are imposed, and some hierarchies of Petri net
languages are obtained. For $\lambda$-labelled Petri nets
a new normal form is derived. It is called the Super-Normal
Form of Petri nets and it improves the Pelz's normal form,
with respect to the interleaving semantics.}
