I realize this is an old thread, but there was something I'd looked up when this thread was new and wasn't certain about.

<xsl:variable name="num1" select="//test1/somevalue1"/>

(The compiler can't automatically convert one to the other, because some expressions treat them differently, for example boolean($num1) is always true in the first case, but in the second case it is true only if //test1/somevalue1 selects at least one node).

What I've never quite understood is how to wrap this into a conditional.

Based on http://www.dpawson.co.uk/xsl/sect2/N8090.html#d9711e895 example, would this be correct for wrapping an assignment in only if a variable was passed in, otherwise using the default?

<xsl:variable name="n">  <xsl:choose> <xsl:when test=="//test1/somevalue1"> <xsl:variable name="num1" select="//test1/somevalue1"/> </xsl:when> <xsl:otherwise> <xsl:value-of select="20"/> </xsl:otherwise> </xsl:choose> </xsl:variable>
