Yes but they don't have to be stored in the MContainer-Elements but then
MPerspective should have an attribute MPerspctive#detachedWindows.

Elements who implement from MPSCElement AND MWindowElement:
* MPart
* MPartSashContainer

Elements who only inherit from MWindowElement are:
* MPerspectiveStack
MWindowTrim from NONE but gets its extra space in MWindow#trims
