Indeed... but basically it's not what I want becuse of the fact that
in my real world case (not the stupid little example) I want to pass
upt to 7,8 parameters.... the syntax
choose-when-/when-otherwise-/otherwise-/choose is more than a little
bit stupid for this...

this I don't understand. what if I want to do something like 
<table bgcolor="#ff0000" border="1"> and have both overridden?

And I don't understand this, too :-(
why don't you need a test for existence in this example around the
xsl:copy-of ?
