  The purpose of this article is twofold: first of all, we want to define two
norms using the space of intrinsically Lipschitz sections. On the other hand,
we want to generalize an Extension Theorem proved by the author in the context
of the intrinsically H\"older sections with target a topological space $Y.$
Here our target will be $Y\times \R^s$ with $s \geq 1$ instead of $Y.$
