It's to do with the number of other associations attached to the widget
on the same side or diagonal of the widget, from which the exact position
of the association is calculated.  I think.

>From associationwidgetdata.h

	/**
	* 	The total amount of associations on the region widget a
line is on.
	*/
	int m_nTotalCountA;

	/**
	*	The total amount of associations on the region widget b
line is on.
	*/
	int m_nTotalCountB;

That sounds about right.

I should point out, incase you're under any dilusions, that the XMI isn't
very scrict or valid XMI.  But then again neither is the XMI from any
other programme.
