If carying the information down the tree is too much effort, it may be
simpler to leave it at the top, and just send back for it when you need
it.

ie rather than

<xsl:template match="A">
<xsl:apply-templates>
  <xsl:param name="label" expr="true"/>
</xsl:apply-templates>
<xsl:template>


<xsl:template match="B">
<xsl:apply-templates>
  <xsl:param name="label" expr="false"/>
</xsl:apply-templates>
<xsl:template>

and then all templates explicitly handling a parameter $label,
you can do

<xsl:template match="A|B">
<xsl:apply-templates/>
<xsl:template>


and then, when in the first version you actually used $label, rather
than just passing it on, now  go

  <xsl:if test="from-ancestors-or-self(A)">
