Jeff:
If I understand you correctly, this is one way to do what you want. It uses an internal lookup table. <local:true xmlns:local="local-namespace"> <value>1</value> <value>true</value> <value>t</value> <!-- all your true values go in here --> </local:true> <xsl:template name="cast-boolean"> <xsl:param name="b-value" select="'false'"/> <xsl:variable name="true-values" select="document('')/*/local:true/value"/> <xsl:choose> <xsl:when test="$b-value = $true-values"> <!-- return true --> </xsl:when> <xsl:otherwise> <!-- return false --> </xsl:otherwise> </xsl:choose> </xsl:template> Note that this approach is tolerant of unlisted values, returning false for them. It can be extended to be more choosy about these, however, by adding a second node set for the false values. It works by using observing that in XPath, a string equals a node-set if its value equals the value of one of the nodes in the node set. I'm not sure this is what you want, however: if not, please be more specific about what you mean by "cast". You want any of a set of values to resolve as true, correct? (And any of another set to resolve as false?)
