Yes, or a hack that uses a single global parameter to pass in a string
containing the list of params that gets tokenised to extract the
different values for each entry point, eg:

<xsl:param name="str" select="'foo=bar;baz=bop;'"/>

<xsl:template name="entrypoint1">
  <xsl:param name="foo" select="f:getParam('foo')"/>

<xsl:template name="entrypoint2">
  <xsl:param name="baz" select="f:getParam('baz')"/>

etc.

So for -it=entrypoint1 you can pass in $str = 'foo=bar', and for
-it=entrypoint2 you pass in $str = 'baz=bop'
