James posited a solution to one of my problems that would solve your problem:

I suppose your solution would then be:

<xsl:template match="METHODREF">
  <xsl:constant name="where-am-i" value="{@name}"/>
  <xsl:value-of select="ancestor(CLASS)/METHOD[@name=constant(where-am-i)]"/>
</xsl:template>

I don't think it can be done today.  I'm hoping to see this feature added
to XSL.

Is there anything preventing you from using ID/IDREF instead?  That would
work fine with today's XSL.
