Yes indeed, itʼs finally rather easy to find:

(again) writes notably (as of the present topic; translation follows below):

| aLigature
| […]
| Le fichier kbd.h ne contient que 4 types LIGATURE2, LIGATURE3, LIGATURE4, 
| LIGATURE5. Mais en réalité on n’est pas limité à cinq unités de code : si on a

| 
| TYPEDEF_LIGATURE(10) // LIGATURE10, *PLIGATURE10;
| static ALLOC_SECTION_LDATA LIGATURE10 aLigature[] = {
| […]
| };
| 
| On peut donc créer des touches renvoyant des mots, voire des phrases. 
| On est toutefois limité à seize unités de code TYPEDEF_LIGATURE(16).

“The kbd.h file contains only 4 types LIGATURE2, LIGATURE3, LIGATURE4, LIGATURE5.
But in reality one is not limited to five code units: if AltGr + space generates 
ten code units, e.g. as in ‘*LIGATURE*’, the table above can be declared as follows:
TYPEDEF_LIGATURE(10) // LIGATURE10, *PLIGATURE10;
static ALLOC_SECTION_LDATA LIGATURE10 aLigature[] = {
[…]
};
Thus we can create keys generating words or even sentences. However we are 
limited to sixteen code units: TYPEDEF_LIGATURE(16).”

As of retrieving this page, it is actually the 18th result of Bing Search on 
'keyboard layout creation', results in all languages enabled.
