This can be done using a config file where you can set the rules to work.
Main xml file:
<mux>
  <set1>1</set1>
  <set2>0</set2>
</mux>

XML config file:
<config>
  <set name="set1" on="1">
    <letters>
      <letter value="a"/>
      <letter value="b"/>
    </letters>
    <numbers>
      <number value="0"/>
      <number value="1"/>
      <number value="2"/>
      <number value="3"/>
    </numbers>
  </set>
  <set name="set2">
    <letters>
      <letter value="x"/>
      <letter value="y"/>
      <letter value="z"/>
    </letters>
    <numbers>
      <number value="0"/>
      <number value="1"/>
      <number value="2"/>
      <number value="3"/>
      <number value="4"/>
      <number value="5"/>
    </numbers>
  </set>
</config>

Stylesheet:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output method="text"/>
  <xsl:template match="mux">
    <xsl:variable name="cnfg" select="document('config.xml')/config"/>
    <xsl:apply-templates select="document('config.xml')/config/*">
      <xsl:with-param name="sets" select="current()/*"/>
    </xsl:apply-templates>
  </xsl:template>
  <xsl:template match="set">
    <xsl:param name="sets" select="/.."/>
    <xsl:apply-templates mode="mux" select="$sets[name()=current()/@name and
normalize-space()=current()/@on]">
      <xsl:with-param name="letters" select="current()/letters"/>
      <xsl:with-param name="numbers" select="current()/numbers"/>
    </xsl:apply-templates>
  </xsl:template>
  <xsl:template match="*" mode="mux">
    <xsl:param name="letters" select="/.."/>
    <xsl:param name="numbers" select="/.."/>
    <xsl:for-each select="$letters/letter">
      <xsl:variable name="letter" select="@value"/>
      <xsl:for-each select="$numbers/number">
        <xsl:value-of select="$letter"/>
        <xsl:value-of select="@value"/>
        <xsl:text> &#10;</xsl:text>
      </xsl:for-each>
      <xsl:text>&#10;</xsl:text>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

Hope this helps you.
