S1000D and S-Series
Applicability

What Applicability Means
No fleet is uniform. Serial ranges differ, modifications land on some tail numbers and not others, and operators configure the same platform differently. Applicability is how a structured library handles that as data rather than as a page of asterisks and footnotes.
Done well, a reader sees only what applies to the aircraft in front of them, and the system can prove why. Done badly, or done as free text, it becomes the most expensive kind of technical debt, because the errors it produces are exactly the errors that reach a technician working on the wrong configuration.
