Element
    ipcEntry - a "flat" IPC Entry
Structure
    ipcEntry may contain, in general:
    1. various textual elements, i.e. content reflecting the changes
        e.g. (list is exhaustive on current compilation files)
        - textBody: for new and deleted entries
        - title: for modified entries
        - flatNotes: modified notes, with non-embedded note structures

    2. amendment element(s), that documents the revision-specific details,
    i.e. the changes made to the entry since the start of the revision period.

    ipcEntry is not embedded into its hierarchy as reflected in the scheme,
    so the ipcEntry-es are flat.

Attributes:
    entryType:   K(lassifying), I(ndexing), D(double) (IPCR_SCHEME)
    ipcLevel:    C(ore), A(dvanced)
        C:  in case the embedding ipcEntries is ipcLevel='a':
            the advanced level version of the entry, which is or is planned to be a valid core level entry
            during revision a new entry marked with ipcLevel='C' is not a valid core entry
            in case the embedding ipcEntries is ipcLevel='c'
            the core level version of the entry, which is a core level entry
        A:  the entry is an advanced level entry

        Other attributes are not used and kept for compatibility to former versions or for later developments.

    kind:
        s(ection)
        t(itle: subsection title)
        c(lass)
        (s)u(bclass)
        g(uidance header)
        m(ain group)
        1-B (dot group, 1 to 11 dots)
        d(eleted)
        (subclass) i(ndex)
        n(ote)

    symbol:    symbol or start of scope for notes and guide headings,
                in format A99AZZZMGGZZZZ (zero padded, 4 digit for main group, 6 digits for group)
    endSymbol: end of scope, in case of note, guide heading and deleted
    coreOfEntry:    symbol of associated core entry in the edition to which the entry belongs
                in format A99AZZZMGGZZZZ (zero padded, 4 digit for main group, 6 digits for group)
    renumberedFrom: symbol from which renumbered (RIPCIS only)
                in format A99AZZZMGGZZZZ (zero padded, 4 digit for main group, 6 digits for group)
    isDead: Y when the text of the entry is deleted by an amendment
            for non-structure entries: remove the entry from the translation
            for structured entries: the entry is removed from the core or the modifications related to the actual level are not submitted for publication
    amendmentType: type of the latest amendment
            Modification of structured entries
            n          new structured entry
            m          m-type (minor) modification of a structured entry
            c          c-type (considerable) complex modification of a structured entry
            s          structure modification of a group (implies c-type modification)
            e          entry type modification (i.e. indexing to classifying or vice versa)
            u          unchanged structured entry
            p          change priority of a structured entry
            c          core to advanced or advanced to core modification
            r          renumber (i.e. change symbol before publication)
            d          delete structured entry
            Modifications of unstructured entries

            D          delete unstructured entry
            Undoing decisions
            0          restore to original (undelete or undoing modifications)
            1          undo a deletion
            2          delete new entry

    source: in output files, the source file from which the actual file was generated
    edition: comma-separated list of versions (aka editions) 
        the editions are dates, in YYYYMMDD format
