    \item The \texttt{FE\_NedelecSZ} class that contains our 
     implementation of the N\'ed\'elec element using the orientation 
     scheme of \cite{Zag06} now supports the computation of hanging 
-    node constraints for locally refined \todo[inline]{hexahedral?} meshes.

-    hexahedral N\'ed\'elec elements in the presence of hanging edges

-    we refer to \cite{Kinnewig2024}. 
-    The \texttt{FE\_NedelecSZ} class and the hanging node constraints 
-    automatically account for the presence of hanging edges and hanging 
-    faces; therefore, there is no difference for the user when using
