Ahh, so must fall back to string comparison.  I figured as such, but
wanted confirmation.  Thanks!

I have a parameter which will either be, true() by default or 'true'
(set by user).  Given the name isTrue, how do you properly write the
if test below:

<xsl:param name="isTrue" select="true()"/>
<xsl:if test="$isTrue or isTrue=true()">

When user sets the param value = 'false' the above isTrue test still
passes.

Right ... because most tools pass user-specified parameter values as
strings, and any non-empty string tests as true.

In your situation I would do for XSLT 1.0:

 <xsl:param name="isTrue" select="'true'"/>
 ...
 <xsl:if test="$isTrue='true'">...

If you are using XSLT 2.0 I would cast the passed value using xsd:boolean()
which has a value set of four strings '1', '0', 'true' and 'false'.

I hope this helps.
