    If those "other formats" are smart enough to handle correctly "<sup>"
    present in HTML sources, then they should be able to handle correctly the
    text hidden by display styles:

    * MS Word and RTF for example can represent hidden text correctly and treat
    it as such, without even needing to filter it completely
    * DocBook can also apply its own XML markup to keep the "hidden" text in XML
    sub-elements (remember that DocBook is not a visual format, but specifies
    the logical structure of a document along with its annotations and
    meta-data), so that it could be regenerated when the DocBook document is
    transformed to HTML.
