What I'm trying to accomplish with the Filter
parameter is to dynamically pass into the stylesheet a
XPath expression to be evaluated.
For example:
<xsl:param name="Filter" select="@rebate>9.99 and
@shippingMethod='Ground' and @cost<199.99"/>
<xsl:apply-templates
select="/Cat[(_at_)CatId=$Cat]/Prod[$Filter]"/>
Thanks.

so Filter is the boolean value true or false
depending on the value of
the rebate attribute at this point.
<xsl:apply-templates
select="/Cat[(_at_)CatId=$Cat]/Prod[$Filter]"/>
If Filter is true it will have no effect but if
Filter is the boolean
value false then this selct will not slect anything.
either way Filter is a constant value not depending
on the path so this
is the same as
<xsl:if test="$Filter">
<xsl:apply-templates
select="/Cat[(_at_)CatId=$Cat]/Prod"/>
</xsl:if>
