The xsl:apply-imports element is used in conjunction with imported stylesheets. There
            are no attributes. The element may contain zero or more xsl:with-param elements (as permitted
            in XSLT 2.0).
         
At run-time, there must be a current template. A current template is established when
            a template is activated as a result of a call on xsl:apply-templates. 
            Calling xsl:call-template
            does not change the current template. Calling 
            xsl:for-each or xsl:for-each-group
            causes the current template to become null.
         
The effect is to search for a template that matches the current node and that is defined in
            a stylesheet that was imported (directly or indirectly, possibly via xsl:include) from the
            stylesheet containing the current template, and whose mode matches the current mode.
            If there is such a template, it is activated using the current node. If not, the call on
            xsl:apply-imports has no effect.
         
To supply parameters to the called template, one or more xsl:with-param elements
            may be included. The values of these parameters are available to the called template. If the
            xsl:with-param element specifies tunnel="yes", then the parameter is passed
            transparently through to templates called at any depth, but it can only be referenced by an
            xsl:param element that also specifies tunnel="yes". If the default value,
            tunnel="no" is used, then the parameter value is available only in the immediately
            called template, and only if the xsl:param element specifies tunnel="no"
            (explicitly or by defaulting the attribute).
