Class UML 2.4.1::Signal
Description:
A signal is a specification of send request instances communicated between
objects. The receiving object handles the received request instances as
specified by its receptions. The data carried by a send request (which
was passed to it by the send invocation occurrence that caused that request)
are represented as attributes of the signal. A signal is defined independently
of the classifiers handling the signal occurrence.

RedefinableElementIndicates whether it is possible to further redefine a RedefinableElement.
If the value is true, then it is not possible to further redefine the RedefinableElement.
Note that this property is preserved through package merge operations;
that is, the capability to redefine a RedefinableElement (i.e., isLeaf=false)
must be preserved in the resulting RedefinableElement of a package merge
operation where a RedefinableElement with isLeaf=false is merged with a
matching RedefinableElement with isLeaf=true: the resulting RedefinableElement
will have isLeaf=false. Default value is false.
Default value: FALSE
