I can't speak to your result with Oracle or Saxon 5.3.2, but I can't
replicate your finding with Saxon 5.5.1 and the stylesheet that you
posted. Whatever I do, it gives False. Can you give the source XML for
the "with 'abc'" test where you found Saxon 5.5.1 giving True?

Can you post the situation where you found this?  In Saxon 5.5.1,
running the following template:

<xsl:template match="/">
   <xsl:variable name="NaN" select="number('abc')" />
   String value of NaN: <xsl:value-of select="$NaN" />
   String value of boolean value of NaN: <xsl:value-of select="boolean($NaN)" />
   String value of boolean value of string value of NaN: <xsl:value-of select="boolean(string($NaN))" />
   String value of numerical value of boolean value of NaN: <xsl:value-of select="number(boolean($NaN))" />
   String value of numerical value of boolean value of string value of NaN: <xsl:value-of select="number(boolean(string($NaN)))" />
</xsl:template>

gave me:

   String value of NaN: NaN
   String value of boolean value of NaN: false
   String value of boolean value of string value of NaN: true
   String value of numerical value of boolean value of NaN: 0
   String value of numerical value of boolean value of string value of NaN: 1

Confused,

Jeni
