        EPO PatXML style ONLY for three levels and ONLY in the description:

        Notes:
        This can be free text data without any structure -<text>(#PCDATA) which is NOT

        (generally) according to ST.14 and ISO 690 layout. This is one of the most
        diffcult areas to standardise as there is no concensus regarding the best way to
        layout a bibliographic citation. We generally adopt to WIPO ST.14 and AACR2

        ARTICLE CITATION
        *******************************

        Article citations within a 'host' document

        After patent citations the most common citations are articles within serials
        (periodicals, magazines), books and electronic (eg. internet) sources).
        This is a very complex and varied area to standardise. The tag set below is drawn
        from a number of sources as is the order of the tags (which in any case can be
        changed depending on the stylesheet used).

        EPO and PatXML usage:

            id="ncit0001"  or id="sr-ncit0001"
            num="0001"
            npl-type="s"

        The order of tags is (generally) that of WIPO ST.14 / ISO 690 layout:

        Examples:

        DROP, J.G. Integrated Circuit Personalization at the Module Level. IBM tech. dis. bull.
        October 1974, Vol.17, No.5, pages 1344 and 1345, ISSN 2345-6789.
        [XPnnnnnnnnnnn].

        This is image data or coded according to mathml, version 2

        ** Added 2006-02-08 - <text> as alternative to image for very simple
        maths which do not need rendition and the "heavy coding" of
        mathml, eg. 2 x 2 = 4

        The top-level element "math" contains MathML encoded
        mathematics. The "math" element has the browser info
        attributes if it is also the browser interface element.

            - If parent element is abstract: id="matha01"
            - num="0001", 0002, etc. OR
                - use the value given by the applicant, usually in
                parenthesis to the (right) side of the formula, eg. (1)
