Defining a stereotype in a profile with an attribute of Enumeration type, and setting the Multiplicity to something greater than 1 - I hopped to be able to select several enum values for that tag in the model at an element assigned this stereotype.
But I can select only one item.
Example:
The metaclass Class is extended by the stereotype "SW Unit" with the attribute "System Variant" of enum type [TINY, SMALL, MID, SIZED, HUGE]. In the model, applying "SW Unit" stereotype to some class, e.g. Ethernet, I would be able to set the tag "System Variant" to MID, SIZED, HUGE, telling that systems of TINY and SMALL do not host a class named Ethernet.
Why does Multiplicity not work for tags with enumerations? (workaround would be to define the attribute in the profile as to be String, but in that case I'll loose the choices pull-down and have to remember all value options)
