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.

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">
<!--Conditionally instantiate a value to be assigned to the variable -->
<xsl:choose>
<xsl:when test=="//test1/somevalue1">
<xsl:variable name="num1" select="//test1/somevalue1"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="20"/><!-- ...or a "20" -->
</xsl:otherwise>
</xsl:choose>
</xsl:variable>

(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.
