Hello Daniel,
no it cannot. If you want to use FECollection, you also have to use the
other parts of the hp-namespace, e.g. hp::DoFHandler, hp::FEValues,....
If you use FESystem, then all FiniteElements contained in the FESystem
are active on all cells, but if you use FECollection, then there is a
pointer for every cell, which points to exactly one FiniteElement
contained in FECollection, which is then active on this particular cell.
Best Regards,
Markus

The subject basically says it all. I see FESystem inherits from
FiniteElement, so an FESystem can take the place of a FiniteElement
object in an FECollection, but I don't see that FECollection can be
used interchangeably with a FiniteElement object - can it?
