Re: regexs, grouping (?) and XSLT2?

OK, going back to this:

I decided to make things simpler and just make the stylesheet 
configurable internally, and then maybe later I can worry about reading 
an external (XML) configuration file.
Does the below seem like the right approach?  And conceptually how do I 
think about reading a non-xsl file and getting the xslt to apply the 
below logic?
<!-- begin configuration options -->

<!--
biborder template called by main bib template to determine order of 
processing
Note: this of course leaves the author-year ordering fixed; not a 
problem now, but would be
if I want to allow greater configuration options.
-->

<xsl:template name="biborder">
  <xsl:apply-templates select="mods:titleInfo"/>
  <xsl:apply-templates select="mods:originInfo"/>
  <xsl:apply-templates select="mods:relatedItem"/>
  <xsl:apply-templates select="mods:location"/>
</xsl:template>

<!-- punctuation variables -->

<xsl:variable name="title-before">
  <xsl:text>“</xsl:text>
</xsl:variable>

<xsl:variable name="title-after">
  <xsl:text>” </xsl:text>
</xsl:variable>

<xsl:variable name="year-before">
  <xsl:text>(</xsl:text>
</xsl:variable>

<xsl:variable name="year-after">
  <xsl:text>) </xsl:text>
</xsl:variable>
<xsl:variable name="creator-before">
  <xsl:text></xsl:text>
</xsl:variable>

<xsl:variable name="creator-after">
  <xsl:text> </xsl:text>
</xsl:variable>

.... etc.
