Template talk:Parameter

I was having a look at some of the templates around here, and I noticed this one from Template:Boss. I was wondering, first, to check that I have it right, gives text ToolTip which shows 1st parameter, and on hover shows 3rd parameter (or just 1st parameter otherwise), then 2nd parameter after the dash.
 * Would we replace with  instead?
 * And I didn't realise it gave a ToolTip that shows Optional/Required until I went over here and looked at the source code, so I think Optional/Required should instead show in brackets like used on this very page's description instead:
 * Parameter Name —  (Required)  This is the name of the parameter in question.
