Subject: RE: [dita] Thoughts On Sections
This discussion really addresses a critical conundrum with DITA in general. The line of thinking that stresses writing reusable concise topics is admirable. For users just adopting DITA, one of their biggest concerns is how they migrate their existing content into DITA. If the integration of legacy content requires huge rework, only the largest, most well-financed groups will take that the plunge. I think this tips the argument in favor of the approach Paul has suggested. It accommodates both points of views. It enables new content to be created expeditiously for single-sourcing and allows legacy content to be imported with less effort.

In most cases, the nesting into two or more levels of information is a formalism preferred by the writer rather than a useful construct for the reader. In most instances, when I review these structures, they are poorly structured. I know that we can't enforce good writing practices, but it's interesting to think we might try. If the authors were asked to write smaller conceptual topics, with better structuring of information to make the information more flat (and therefore perhaps more understandable), we could stay with the original design. If the nesting is really that important to understanding in the output context, the nesting could occur in the ditamap rather than in the topic itself. The smaller conceptual topics would also be more readily available for reuse in contexts where they should be standalone. Just some thoughts JoAnn JoAnn T.

My personal opinion on the current section element is that they are simultaneously too strict and too loose. We've discussed at length the sense in which they are too loose: they do not provide any guidance for authoring and overlap almost exactly with the content model of paragraph. On the other hand, sections are more strict than HTML "DIV" elements in a very important way: they cannot be nested. Some of our customers have a need for "grouper sections" that can wrap up other sections in their specializations. Basically their topics are not necessarily flat. For privacy reasons I'll make up an example structure: Part Description Subparts Subpart 1 description Subpart 2 description Subpart 3 description Use contexts Context 1 description Context 2 description Context 3 description The customer sees the "Part Description" as the topic level because the subparts are meaningless to the reader out of context of the parent. Therefore I feel that in the loose, designed-to-be-specialized base DITA topic type, sections should be nestable. Another key reason to allow sections to nest is to have a body-level container that can serve the "generic wrapper" role that phrases do at the inline level. Generic wrappers are useful as a basis for specialization, as a place to put filtering attributes and as a way to logically conref a set of content elements at once. I propose short-term and long-term directions for sections: DITA 1.1: they should be loosened to be generic wrappers that can nest. <!ENTITY % section.cnt "(#PCDATA | %basic.ph; | %basic.block; | %title; | %txt.incl; | section)*"> DITA 2.0: they should be tightened to be generic wrappers _of body elements_ with zero or one titles and no PCDATA. <!ELEMENT % section.cnt "(title? , %basic.block;)"> If we could agree on this direction then we wouldn't need a new structured-section element. But if it is important that section have basically the same content model as paragraph plus titles (I'm not sure why) then we probably do need structured-section. Paul Prescod
