A parameter has to be declared in the template
before you can pass a value to it.  So you
just need:

<xsl:template name="a.procedure">
  <xsl:param name="formal.procedures" select="0"/>
  [rest of template]

This puts the parameter "formal.procedures" in scope this
that template.  This  statement also gives you an
opportunity to set a default value, which is overridden
when you call the template "with-param".
