Re: [xsl] <xsl:for-each select="$myvar">

["James Fuller" <james.fuller@xxxxxxxxxx>]

<xsl:param/> is used to inject values from the outside world into XSLT

in addition, they have a dual role of serving as a mechanism to inject a
variable into a template, named or otherwise

<xsl:param/> is declared as a global variable or template variable whereas
<xsl:variable/> adheres to within its scope
