[xsl] Use of Select in Params

["Karl Stubsjoen" <kstubs@xxxxxxxxx>]

You know, the use of a select in param definitions has always confused
me.  Could someone explain them, maybe a simple example?  Also, the
select for the param, does it have an effect on the data passed into
it (if it is a node litst)?
I have frequently used "../" or is it "/.." to guarantee that the
param should be interpreted as a node-list.

Thanks,
Karl..
