XSLT 2.0 default.table.column.widths error

I just started using the standard stylesheets for 2.0.3 and
    attempted a FO transformation using fo/docbook.xsl with Saxon 9-HE.
    I get an error that "Variable default.table.column.widths has not
    been declared. The error is generated from the file
    common/table.xsl. The variable is in html/param.xsl. Is that param
    in the correct directory? Is my transformation setup OK?
