In the UML superstructure specification v2.3, the syntax for the Message name is the following:
<messageident> ::= ([<attribute> ‘=’] <signal-or-operation-name> [‘(‘ [<argument> [‘,’<argument>]* ‘)’] [‘:’ <return-value>]) | ‘*’

<argument> ::= ([<parameter-name> '='] <argument-value>) | (<attribute> '=' <out-parameter-name> [':' <argument-value>] ) | ' -'


This syntax allows the display of arguments like operation paramter values and return values.
