I am using saxon and just found that initializing a template parameter
with an empty nodeSet, like this

<xsl:param name="myNodes" select="/.."/>

causes saxon to throw a nullpointer exception.

The same code works fine with lotus-xslt.

A simple solution is to select some node which isn't actually present 
in the input file, like this

<xsl:param name="myNodes" select="/dummy"/>

works for both tools.
