| SAXONICA | 
The xsl:decimal-format element is used at the top level of a stylesheet to indicate a set of localisation
            parameters. If the xsl:decimal-format element has a name attribute, it identifies a named format; if not, it identifies the
            default format.
         
In practice decimal formats are used only for formatting numbers using the
            format-number() function in XPath expressions.
            For details of the attributes available, see the XSLT specification.
