Just thought that one of the techniques I am using in my "stylefree 
stylesheets" can apply here...

What about diverting unnamed templates to use them as "variably named" 
templates using hook nodes in the XSLT sheet itself to match the 
variable names ?

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:vn="http://dyomedea.com/ns/variable-names";>

<!-- just a shortcup... -->
<xsl:variable name="varnames" 
select="document('')/xsl:stylesheet/vn:templates"/>

<!-- hooks -->
<vn:templates>
  <vn:template1/>
  <vn:template2>I am template 2</vn:template>
  <vn:template3>
	<info> Some more info for template 3</info>
  <vn:template3>
</vn:templates>

.../...

  And instead of <xsl:call-template name="$abc"/>,

  <xsl:apply-templates select="$varnames/*[local-name()=$abc]"/>

or when the context node is important:

  <xsl:apply-templates select="$varnames/*[local-name()=$abc]">
    <xsl:with-param name="context" select="."/>
  </xsl:apply-templates>


and

   <xsl:template match="vn:template1">
...

That can do the trick for a number of applications and you can pass 
additional info to your templates in the "hook" elements.
