Well, as i said in the first post, is possible that the number of vars will
grow
to a number i do not know at this time...
are you sure that you need any variables at all?
You could use something like the following setup which is variable free...
<xsl:stylesheet ...
xmlns:x="anything"
<x:x name="pages" elem="FormZoom"/>
<x:x name="params" elem="ParametroZoom"/>
...
<xsl:template ...>
<Event method="nextPage" target="btnProceed" type="ActionHandler">
<xsl:for-each select="document('')/*/x:x">
<xsl:attribute name="{(_at_)name}">
<xsl:for-each
select="/Formatos/Forms/Form/Grids/Grid/Zooms/Zoom[(_at_)Coluna!='xxx']/*[name()=current()/@elem">
<xsl:value-of select="."/>
<xsl:text>:</xsl:text>
</xsl:for-each>
</xsl:attribute>
</xsl:for-each>
</Event>
....
