Isn't there a way to do this uniformly, for any Reader? That would be much preferred.
I think I might be able to do what I need with a custom ErrorHandler. The downside is that it exposes only error message, and not the raw URI value. Couldn't the violations be passed to Model and then exposed as List<Violation> getParseViolations() or smth? That is probably not clean from the abstraction point of view, but where Model is the only contract, passing other information along gets complicated.
