I have a boolean parameter and wonder if there is a "preferred" style for setting it to 'false':
These two work but seem indirect and verbose:
<xsl:with-param name="set-current">
<xsl:text>false</xsl:text>
</xsl:with-param>
or
<xsl:with-param name="set-current" select="not('true')"/>

I don't know why the first works. boolean($set-current) will return true, as will boolean() applied to any non-empty node-set.

The second is fine: not() applied to any non-empty character string returns true. But writing false() is simpler.
