 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

 Inside this element should be a `<head/>` enclosing the headword of the article.
 The usual sub-`<hi/>` elements are available within `<head/>` if the headword is
 highlighted by any special typographic means such as bold, small capitals, etc.
-This element should also contain the optional subject indicator within
-parenthesis that sometimes accompany the headword, with the appropriate standard
-elements like `<persName/>` occurring in biographical articles or `<interp/>`
-with a `theme` attribute if the article is given a specific domain in a

+The one disappointment of the encoding scheme we are currently defining is the
+lack of support for a proper way to encode subject indicators.
+
+The best candidate we have found so far was `<ùsg/>` from the *dictionaries*
+module but it is not available directly under a `<head/>` element. All inclusion
+paths from the latter to the former of length less than or equal to 3 contain
+irrelevant elements (`<cit/>`, `<figure/>`, `<castList/>` and `<nym/>`) so it
+must be discarded. The next best elements appear to be `<term/>` (not very
+accurate) and `<rs/>` ("referring string", quite a general semantics but a
+possible match — subject indicators refer to a given domain of knowledge —
+although all the examples in the documentation refer to concrete persons,
+places or object, not to the abstract objects that mathematics or poetry can be)
+
+For this reason, we do not recommend any special encoding of the subject
+indicator but leave it open to each particular context: they are often
+abbreviated so an `<abbr/>` may apply, in *La Grande Encyclopédie*, biographies
+are not labeled by a knowledge domain but usually include the first name of the
+person when it is known so in that case a element like `<persName/>` is still
+appropriate.
