StdProps and Collections

[Mike Ginou <mikeginou bigfoot com>]

Do the standard property dialogs for programmed objects offer any support
for collections (as with the UML attributes, for example)?

As I understand it, Dia's UML objects are not considered good examples for
creating new objects. However, the UMLClass object is the only example I
have found that includes properties which are collections (again like the
UML Attributes or Operations).

Is a custom dialog necessary to support (unusual) collections properties.
