I had already the apprehension! But if it is so, I can't help you too. The
only thing, what I can suggest, is, changing your <xsl:if>  to the following:

<xsl:if test="number(@attribute2)"> 
    <xsl:value-of select="format-number(@attribute2,"#,###.00")"/> 
</xsl:if> 

So text-values of @attribute2 won't be formatted to NaN too.
