What does obligatoriness mean?
Obligoriness is the noun meaning the quality of being obligatory, compulsory, or binding. It names a property rather than the specific requirement itself: the obligatoriness of a deadline differs from the content of the deadline, while the obligatoriness of a legal duty concerns whether compliance is required. The word is especially associated with formal, legal, institutional, or procedural contexts and may sound somewhat technical outside them. In general prose, alternatives such as “compulsoriness,” “mandatory nature,” or “compulsory character” can often sound more natural. Obligoriness is useful when discussing the degree to which something leaves no genuine choice, especially where it is important to distinguish the binding character of a rule from the practical consequences of following or violating it. Although it is uncommon, the word provides a precise nominal counterpart to “obligatory” and belongs to the same English and Latin family as “obligation,” “obligate,” and “oblige.”

"The policy left no doubt about the obligatoriness of the mandatory safety check."
"The optional briefing nevertheless emphasized the obligatoriness of the annual safety check."

The plural is rare and is appropriate when separate obligations or requirements are being treated as distinct instances.
"Critics questioned the obligatorinesses of several clauses, not merely their wording."
Obligoriness is what remains when “must” stops being a word and becomes a fact.

Where does obligatoriness come from?
Obligoriness was formed in English from obligator-, as in “obligatory,” together with the noun suffix “-ness.” Its deeper source is Latin obligatorius, meaning “binding” or “obligatory,” derived from obligāre, “to bind” or “tie,” which was itself built from ob- and ligāre, “to bind.” The same Latin root produced related English words including “obligation,” “obligate,” and “oblige.”
