Notes for DALF guidelines for the description and encoding of modern correspondence material Version 1.0
Concerning the elements included from the additional TEI tagsets: all elements from the Linking, figures, transcr, and textcrit additional tagsets were included. Of the Analysis additional tagset, only <interp> and <interpGrp> were included. Of the names.dates additional tagset, only <placeName>, <settlement>, <region>, <country>, <bloc>, and <distance> were included.
This section will discuss the specific extensions of the TEI header that are incorporated in the DALF header. This means that some familiarity with the TEI header is assumed from the reader. We considered it no use to repeat the excellent and comprehensive documentation for the TEI header, the interested (or desperate) reader can find at http://www.tei-c.org/P4X/HD.html. As for the standard TEI elements occurring within specific DALF header elements, a concise explanation is provided, as well as a reference to the full TEI documentation of the elements concerned.
A full technical discussion can be found in Arjan Loeffers answer on 28 October 1997 to Andreas Nolda who formulated nearly the same problem we encountered. These messages can be found in the TEI List archive.
This distribution is based on that of the original TEI <figure> element. Note that there is a slight discrepancy between the TEI documentation of this element (see http://www.tei-c.org/P4X/ref-FIGURE.html) and its declaration in the DTD files. The documentation states that <figure> is a member of only 2 element classes, namely inter and tpParts; whereas the TEI teiclas2.ent file declares <figure> as member of a third element class: common. Since in practice the distribution of <figure> clearly suggested the latter evidence, the DALF scheme also defines all elements whose distribution is modelled after that of the original TEI <figure> element as members of the common, inter, and tpParts element classes.
None of these options provides 100% satisfactory solutions, however. Encoding multiple hierarchies in XML has become a generally acknowledged problem for which a number of other solutions (independent of TEI) are proposed, varying from degrees of ‘virtual markup’ (e.g. standoff-markup, Bottom-Up Virtual Hierarchies) to abandoning XML for another encoding scheme (MECS, TexMECS, Just-In-Time Trees). Up to now, this has not lead to ready-to-use, generally accepted ways of dealing with overlapping hierarchies in XML. Therefore, we stuck to the proposals within the TEI paradigm, which provides after all the best guarantee for future standard-compliance.
In particular, the "suggestions for the forthcoming/ongoing (?) TEI revision" made by Hilde Bøe, Ellen Nessheim and Stine Brenna Taugbø for the Henrik Ibsen's Writings, posted on 4 December 2001. These included (a.o.) the redefenition of <add>, <figure>, and <note> as global elements. Also in his answer of 28 July 2000 to a question regarding the impossibility to use <note> inside <salute>, Syd Bauman describes this as "an error with TEI including the TEI-Lite view", and suggests the option to extend the TEI DTD.
See note 3 for a discussion on the distribution of the TEI <figure> element.
