XRC and dynamically created widgets?

One more quickie question: why does this line have to be written this 
way, with the id keyword argument, instead of like:

xrc.XCRCTRL(self.XXX, 'new RecordMenuItem')

Doesn't the Bind() method take a reference to the object as its third 
parameter? And why is the 'id' necessary? It didn't work when I left it out.
