XSLT Spec Problem

["Jon Smirl" <jonsmirl@xxxxxxxxxxxx>]

When using parameters with template matches, the parameters only last during
the first match made. For example:

<DIV>
<P>
<SPAN>

<xsl:template match="DIV">
     <xsl:apply-templates select="*>
      <xsl:param name="label">true</xsl:param>
     </xsl:apply-templates>
</xsl:template>

  <xsl:template match="SPAN">
      <xsl:param-variable name="label">false</xsl:param-variable>
       ....
  </xsl:template>

This would work as written. Now suppose somebody comes along an adds a match
for <P>

  <xsl:template match="P">
  </xsl:template>

This breaks the stylesheet because the parameters are lost.

Doesn't this make stylesheets containing parameters very fragile to change?
Any one making a change must carefully understand all use of parameters
before making the slightest change to the sheet. In this case the <P> match
needs to be modified to pass the label parameter along, but what if there
were more combos like DIV/SPAN that the P tag would mess up? All of these
variable would have to be passed along.

Could variables be visible to all matches until the select="*" returns?
