Michael,

assuming that the key is in fact referenced do you have any opinion on the
original question: is there a significant performance difference between
passing the same data as parameters or referencing it via a key?  I'm
assuming the reference to the parameter data is pretty direct: Eg:

	<xsl:with-param name="gunk" select"data"/>

Then later:

	<xsl:value-of select="$gunk/anode"/>

In our case we have to pass the parameter data through a total of five
templates before it is finally consumed and the use of the key would be
mostly to simplify the coding of the stylesheet.
