Hi Brian,
I'll respond based on Sanitago's assessment. (He's having trouble
getting mail on the xalan-dev alias).
#1 This seems like a reasonable enhancement. Would you file an
enhancement request in Bugzilla.
#2 This is not really doable giving the compile/runtime architecture
of XSLTC.
#3 This is already supported for nonstatic external Java functions.
There a few ways to call such a function. For example:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xalan-java="http://xml.apache.org/xslt/java";
xmlns:java="http://xml.apache.org/xslt/java";
xmlns:xsltc-java="http://xml.apache.org/xalan/xsltc/java";
xmlns:xalan-java-math="http://xml.apache.org/xslt/java/java.lang.Math";
xmlns:xsltc-java-math="http://xml.apache.org/xalan/xsltc/java/java.lang.Math";>
<xsl:template match="/">
<xsl:value-of select="xalan-java:java.lang.Math.sin(1.2)"/>
<xsl:value-of select="java:java.lang.Math.sin(1.2)"/>
<xsl:value-of select="xsltc-java:java.lang.Math.sin(1.2)"/>
<xsl:value-of select="xalan-java-math:sin(1.2)"/>
<xsl:value-of select="xsltc-java-math:sin(1.2)"/>
<!-- This instruction reports a warning at compile time
<xsl:value-of select="xalan-java:nodeset()"/>
-->
</xsl:template>
</xsl:stylesheet>
