IIRC, the "at this point" language comes straight from the third-party Jing
RelaxNG schema-checking tool that's at the core of the validator. The error
messages that Jing emits are notoriously lacking in helpfulness but more
generally the problem is that any general grammar-based schema-checking
tool is necessarily going to be limited to emitting some fairly generic
boilerplate-ish types of error messages. That's one of the reasons why
these days I've moved more and more of the error-emitting logic out of the
RelaxNG schema and into custom Java code in another part of the sources.
