This works when you only have one parameter; but in the 
general case with N parameters, you have N! cases
to handle with the current method shown above -- by 
allowing the <xsl:choose> inside the <xsl:call-template> 
you avoid all this unnecessary writing.   In my current
application I have 8 parameters in the base function;
each with non-trivial default values.  As a work-around
I've had to make each "default value" a stand-alone
template that is called by the derived function.

Does this explain better?
