UML: TIP: always use a Model (not a Package) for analysis elements and analysis diagrams (that may refer to design elements).

Dr Darren explains:

Given that in MagicDraw™ UML (at least) I usually use «wrapper» Components, not Models, to create restricted views of elements packaged elsewhere, I reserve Model increasingly for analysis elements (although there are some older counterexamples on this site).

If you insist on reserving an analysis Model with ElementImports for a strictly derived (only) "views" of otherwise "physically" packaged analysis elements another approach is:

UML: TIP: ALTERNATIVE: prefix each *Analysis Package with an asterix '*'
