Re: [xsl] A smarter choose operation XSL 1.1

[Karl Stubsjoen <kstubs@xxxxxxxxx>]

Disregard Nan issue for number($optional.one), it was misuse of the
string() function which needs a boolean operation first before the
number operation.

So I had:
<xsl:variable name="optional.one" select="string(firstName)"/>

I needed:
<xsl:variable name="optional.one" select="boolean(string(firstName))"/>
