Yes. I guess this is covered by the 7.6.2 NOTE. But what is misleading
me is the fact that it works exactly as might be expected by not-readers
of this note; for example, the template:
<x:template match="el">
<x:variable name="match-value">
  <x:if test="@attr = 'x'">
    <x:value-of select="'value1'"/>
  </x:if>
  <x:if test="not(@attr = 'x')">
    <x:value-of select="'value2'"/>
  </x:if>
</x:variable>
  <xsl:template match="{$match-value}">
    <xsl:value-of select="foo"/>
    <!--whole bunch of other complicated stuff-->
  </xsl:template>
</x:template>

produces (given the input I previously mentioned), the 2 templates:
<xsl:template match="value1">
  <xsl:value-of select="foo"/>
</xsl:template>
<xsl:template match="value2">
   <xsl:value-of select="foo"/>
</xsl:template>
in all of xalan/saxon/xt/oracle xsl. So at least for the non-readers
of the note (whose carelessness I am not trying to excuse),
the only problem would seem to be getting the right stuff
into these 'value1' and 'value2' strings.

Er, how is that different from what I'm doing here?
