-----------------
Error at xsl:apply-templates on line 67 of
file:/C:/xml/xsleg/xslt/posgroup1.xsl
:
  Invalid element within xsl:apply-templates:
Error at xsl:param on line 69 of
file:/C:/xml/xsleg/xslt/posgroup1.xsl:
  xsl:param must be immediately within a template,
function or stylesheet
Error at xsl:param on line 69 of
file:/C:/xml/xsleg/xslt/posgroup1.xsl:
  Variable is already declared in this template
Error at xsl:param on line 69 of
file:/C:/xml/xsleg/xslt/posgroup1.xsl:
