USE-CASE: Schematron has helped organize the monitorig of services during the COVID epidemic: in the US, real-time data on Emergency Medical admissions and causes is collected by National Emergency Medical Services Information System (NEMSIS). Schematron has allowed them a practical route to having subject-matter experts specify rules in plain English, then developers implement exactly those rules. Read their excellent Schematron Guide, or see their online Library of national and state-level Schematron Rules. (Hint: try “PA”)
