Here is are the test cases:


<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:template match="/">
Case 1:
<xsl:value-of select="format-number('', '###.###')"/>
<!-- outputs NOT "NaN" as expected -->

Case 2:
<xsl:value-of select="number('')"/>
<!-- outputs NaN, ok -->

Case 3:
<xsl:value-of select="format-number(non/existing/path, '###.###')"/>
<!-- outputs NOT "NaN" as expected -->

Case 4:
<xsl:value-of select="number(non/existing/path)"/>
<!-- outputs NaN, ok -->

</xsl:template>
</xsl:stylesheet>



thanks,
Stephan
