Well, the most common method I know of doing that is:
<xsl:param name="foo" select="''"/>
....
<xsl:if test="$foo = ''">
<!-- Test to see if no value has been supplied -->
</xsl:if>
<xsl:if test="not($foo = '')">
<!-- Test to see if a value has been supplied -->
</xsl:if>
You can probably clean this up a bit by using named templates.
<xsl:template name="param.foo">
<xsl:choose>
<xsl:when test="$foo = ''">
<xsl:value-of select="$foo"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="foo"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>

IIRC, by default it adds the query string parameters supplied to the URL, and
any additional parameters added by any AxKit plugins that are supplied. For
instance, you can use one of the Apache::AxKit::Plugin::AddXSLParams::*
modules to put in additional parameters as needed.
Kip wrote a module to parse out the HTTP Request object and supply detailed
parameters for them (::Request) and I have a module that can take values
stored in your BasicSession and supply them to your stylesheet.

Good choice! Its a really great book. I've been an AxKit regular for a while
now, and I've learned quite a few things in there.
