Signal
A signal defines a message that consists of a set of attributes exchanged in an interaction between blocks.
Create signal
You can enter signals manually via a dialog or model them in a block diagram. You can recognize a signal in the system by this icon: 
Stereotype
The stereotype of signal is <<Signal>>. You need the stereotype if you want to create document templates, queries, forms or search for a signal in the tool.
In the Stereotypes window you will find the stereotype under DomainElement. Here you can create further sub stereotypes or user-defined properties. Properties do not have to be created separately for each sub stereotype, since the properties are inherited from the main stereotype.
