It is important to keep in mind the context and the scale. There are specific contexts and specific scales. For example, if funding is granted to towns or provinces, there would be very strong linguistic clauses associated with that funding because those bodies have the ability to comply with them. However, if the funding is for a neighbourhood party and extremely strong linguistic clauses are imposed, no one will apply for funding because they will not know how to comply with those clauses.
The idea is to develop a model that would make it possible to measure the accessibility of an event and to then make people aware of how to make their event accessible. An ironclad linguistic clause is not necessarily how we are going to succeed in making events accessible.
In short, it depends on the context and the scale.
