The reason why I created this variable is because I
need to apply templates to all the Rows in the xml. 

However, the structure of the Rows in xml is a bit
peculiar. I can have 1, 2, 3 or even more RowGrp
elements before the Row elements. 

Since I do not know how many RowGrp elemetns I will
have I cannot do something like this:

<xsl:apply-templates select="Report/Rows/RowGrp/Row"/>
or this

Therefore, I created the variable using the //

<xsl:variable name=set" select="Report/Rows//Row"/>

I also read in some posts that it is faster to use a
node set in a variable. I might be wrong though. Any
suggestion considering that I can have lots of Row and
Cell elements in the xml?

       <Row heading="Name 1">
           <Msr idx="1" val="10" />
           <Msr idx="2" val="15" />
       <Row heading="Name 1">
           <Msr idx="1" val="10" />
           <Msr idx="2" val="15" />

I have noticed that this does not work.

You are right. I want to apply templates to the
children of the current Row node that is in the node
set. But if it is not possible I will have to get rid
of the node set and use only apply templates Cell.
