Proposed syntactic sugar: xsl:propagate-param

Recently, I have written a few stylesheets mostly consisting of
constructs like:

<xsl:template match="*" mode="xxx">
<xsl:param name="a"/>
<xsl:param name="b"/>
<xsl:param name="b"/>
...
...
<xsl:apply-templates>
<xsl:with-param name="a" select="$a"/>
<xsl:with-param name="b" select="$b"/>
<xsl:with-param name="c" select="$c"/>
...
...
...
</xsl:apply-templates>

...
...
</xsl:template>

I would find really useful if there was a way to propagate the params
like:

<xsl:template match="*" mode="xxx">
<xsl:apply-templates>
  <xsl:propagate-param/>
  <xsl:with-param name="c">XXXXXXXX</xsl:with-param>
</xsl:apply-templates>
</xsl:template>


xsl:propagate-param would sent all params which given template accepted
to the template
specified by the xsl:apply-templates or xsl:call-template.

It would be possible to override some of the values with explicit
xsl:with-param
</xsl:template>
