The analogue of msxml:node-set($variable) in the earlier pre-releases of
MSXML3 was $variable. These releases implictly coerced a result tree to
a node set if needed. This implicit coercion was removed in favour of 
forcing users to use an extension function in order to make the system
conform to the spec.

But either way it won't help your problem, There is no way in XSL to
evaluate a string as an Xpath. The only system that I know that provides
this feature is saxon with saxon:evaluate.

Otherwise you have to do two passes, using the value of ActionPath
you first _generate_ a stylesheet with an appropriate 
<xsl:for-each select=
then you apply this generated sheet to your data.

No your ActionPathVar is set with an xsl:variable using a select
attribute, so is _not_ a result tree fragment, it is (in this case)
a node set consisting of the node ActionPath.

Your problem is that 

<xsl:for-each select="$ActionPathVar">

selects the node ActionPath not the node which would be selected by
evaluating the string value of ActionPath as an XPath.
