UML23 — Section: 14.3.20

My question regards the following: 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>] | ‘ -’ First, I see a typo in the argument definition where the beginning of the definition should read as follows (Note the first square bracket and less than symbol): <argument> ::= ([<parameter-name> ‘=’] Second, I would like clarification on this item. From the definition it seems that I cannot specify a message by just showning the parameters. For example, if I have a class that has an operation of setFoo(int value): void, I cannot have a message of the method and its parameters, for example, "setFoo(value)". It would look like this instead "setFoo(value=)" according to the definition in the specification. To me this just doesn't seem right to have this hanging equal sign. There are other examples, pages 458 and 491 for example, that show a parameter without the equals sign. Could someone clarify this for me?

Discussion:
This issue seems to have been fixed already.
