 ### The notion of meaning
 
-### Nested structures
+Notwithstanding the correct way to represent domains of knowledge, their extent
+itself raises concerns regarding the *dictionaries* module. Indeed, among the
+vast collection of domains covered are sometimes historical articles and
+biographies. If the notion of meaning can appear ill-fitting for a text
+describing a series of historical events, one may still argue that it groups
+them into a concept and associates it to the name of the event. But when it
+comes to relating the life of a person, describing their relation to events and
+other persons comes out even further from the notion of meaning. To what extent
+is it relevant to consider that having discovered such or such thing or to have
+been born on a certain time at a certain place *defines* someone ?

+
+Moreover, encyclopedias, inheriting as much as they have from the philosophical
+Enlightenment, are not only spaces designed to assert, they also intrinsically
+include an interrogative component. Some articles lay down the basis required to
+understand the complexity of an issue and invite the reader to consider it
+without providing a definite answer, going as far as to explicitly using
+question marks.
+

+
+In this extract, the author devises a hypothetical situation to illustrate how
+difficult it is to draw the line between two supposedly mutually exclusive
+subcategories of legal actions. The whole point of the passage is to convey the
+idea that the term eludes definition, wrapping it in a `<sense/>`, or worse, a
+`<def/>` element would be an utter misnomer.
+
+As a result, the use of `<sense/>` and `<def/>` is not appropriate for
+encyclopedic content in general.
 
-### Candidates in the *dictionaries* module
+### Nested structures
 
-- `<sense/>`
-- `<entryFree/>`
-- `<note/>`
-- `<dictScrap/>` / `<floatingText/>`
+The final difficulty can be considered as a partial consequence of the previous
+one on the structure of articles. The difficulty to define complex concepts is
+the very reason why authors approach their subjects from various angles,
+circumnavigating it as a best approximation. This strategy favours long,
+structured developments with sections and subsections covering the multiple
+aspects of the topic: from a historical, political, scientific point of view…
+The longest articles can thus span several dozens of pages. They can contain
+substructures with titles on at least three levels (for instance, a `a)` under a
+`1)` under a `I.`), each of which are in turn generally developed over several
+paragraphs.
+

+
+The nested structure that we have just evidenced demands of course a nesting
+structure to accomodate it. More precisely it guides our search of XML elements
+by giving us several constraints: we are looking for a pair of elements, the
+first representing a (sub)section must be able to include both itself and the
+second element, which doesn't have any special constraint in addition to the one
+it shares with the first, which is to have a semantics compatible with our
+purpose. In addition, the first element must be able to contain several `<p/>`
+elements, `<p/>` being the reference element to encode paragraphs according to
+the XML-TEI documentation.
+
+We have seen that the *dictionaries* module was equiped with a questionable but
+possible element for subject domains. However, it does not include any element
+for section titles. In the rest of the TEI specification, the elements `<head/>`
+and `<title/>` — the latter with the possibility to set its `type` attribute to
+`sub` — stand out as the best candidates for the semantics condition on the
+second element.
+
+#### Candidates in the *dictionaries* module
+
+Filtering the content of the module to keep only the elements which can at the
+same time contain themselves, be included under `<entry/>` and include a `<p/>`
+and either the `<head/>` or `<title/>` elements yields absolutely no candidates.
+
+The lack of results from this simple query forces us to somewhat release the
+constraints on the elements we are willing to use. We can for instance make the
+asumption that the occurrence of an intermediate element could be needed between
+the `<entry/>` element and the recursing one used to encode sections. This
+"section" element could also need a companion element to be able to include
+itself, or, to formalise it in terms of graph theory, we could relax the
+condition on this element to admit a loop by considering a cycle of a given
+(small, this still needs to represent a fairly direct inclusion) length to be
+enough. We simultaneously extend the maximum depth of the inclusion paths we are
+looking for between `<entry/>`, the pair of elements and the `<p/>` element.
+
+By setting this depth to 3, that is, by accepting one intermediate element to
+occur in the middle of each one of the inclusion paths that define the structure
+required to encode encyclopedic discourse, we find 21 elements but none of them
+stand out as an obvious good solution: all paths to include the `<p/>` element
+from any *dictionaries* element either contain a `<figure/>` (which we have
+previously encountered earlier when we were practising our graph approach to
+search for inclusions between `<entry/>` and `<entryFree/>` and dismissed as not
+useful in general), a `<stage/>` (reserved to stage direction in dramatic works)
+or a `<state/>` (used to describe a temporary quality in a person or place),
+again not even close to what we want. The paths to either `<head/>` or
+`<title/>` are similarly disappointing. If that is not a thorough proof that
+none of these elements could fulfill our purpose, it is a fact than no element
+in this module appears as an obvious solution and a serious hint to keep looking
+somewhere else.
+
+#### Widening the search
+
+We hence widen our search to include elements outside the *dictionaries* module
+which could be used to encode our sections and subsections, under the same
+constraint as before to try and find a composite solution that would remain
+under the `<entry/>` element even if resorting to subcomponents outside of the
+dedicated module. Only three elements are returned:
+
+- `<figure/>`: not any more useful to represent the content of encyclopedic
+  discourse than as a helper to include paragraphs
+- `<metamark/>`: a very useful device to transcribe the edition marks than may
+  appear on a particular primary source to alter the normal flow of the text and
+  suggest an alternative reading (deletion, insertion, reordering, this is about
+  a human editing the text from a given physical copy of it), again really of no
+  use for a part of an article describing the geology of Europe for instance.
+- `<note/>`: the first element that might at least resemble what we are looking
+  for. It is meant to contain text, is about explaning something and seems
+  general enough (not specific to a given genre, or to the occurrence of a
+  particular object on the page). Unfortunately, its semantics still seems a bit
+  off compared to our need. The documentation describes it as an "additional
+  comment", and, moreover "out of the main textual stream" whereas the long
+  developments in article are the very matter that inhabits the columns of text
+  encyclopedias are made of.
 
 ## Encoding within the *core* module
 
 The above remarks explain why the *dictionary* module by itself is unable to
-represent encyclopedias, where discourse with nested structures of arbitrary
-depth can occur. Since the *core* module of course accomodates these structures
-by means of the `<div/>`, `<head/>` and `<p/>` elements, we devise an encoding
-scheme using them which we recommend using for other projects aiming at
-representing encyclopedias.
+represent encyclopedias, where the notion of "meaning" is less central that in
+dictionaries and where discourse with nested structures of arbitrary depth can
+occur. Since the *core* module of course accomodates these structures by means
+of the `<div/>`, `<head/>` and `<p/>` elements which have the additional
+advantage of carrying less semantical payload than `<sense/>` or `<def/>` we
+devise an encoding scheme using them which we recommend using for other projects
+aiming at representing encyclopedias.
 
 To remain consistent with the above remarks we will only concern ourselves with
 what happens at the level of each article, right under the `<body/>` element.
