Assuming you always treat these variables as strings (rather than as
result tree fragments that you convert to node sets), these are
exactly the same as:

  <xsl:variable name="v_updateProc" select="'$updateProc'" />
  <xsl:variable name="v_canEdit" select="'{$canEdit}'" />
  <xsl:variable name="v_script" select="'{$script}'" />
  <xsl:variable name="v_css" select="'{$css}'" />
  <xsl:variable name="v_class" select="'{$class}'" />

It's easiest if you work backwards. In the XSLT that's the result of
your first stylesheet, you want to have:

  <xslt:if test="$canEdit = 'true'">
    <xslt:call-template name="saveButton" />
  </xslt:if>

You want the "$canEdit" part of the test to be provided from the
$v_canEdit variable in the stylesheet that's generating this XSLT. So
the $v_canEdit variable needs to be set to the string '$canEdit':

  <xsl:variable name="v_canEdit" select="'$canEdit'" />

and the test attribute of the xslt:if literal result element needs to
contain an attribute value template that inserts the value of the
$v_canEdit variable in place of the "$canEdit" part of the test:

  <xslt:if test="{$v_canEdit} = 'true'">
    <xslt:call-template name="saveButton" />
  </xslt:if>

You say that you've tried this; all I can tell you is that it should
work. If it doesn't, try checking the result that you *are* getting to
see what XSLT you're generating to make sure that it's the XSLT you
think you're generating, and try running that XSLT alone (and editing
it as necessary) to see what that XSLT needs to be in order to work.

Cheers,

Jeni
