Hi, We have used EXSLT in C2 stylesheets without problems. Here is an excerpt:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0" xmlns:exslt="http://exslt.org/common";> ... <xsl:if test="exslt:node-set($content)/checkboxes/checkbox[not(@selected)]"> ... As far as memory serves, it worked seamlessly with Xalan and Saxon.
