You should be able to run validators on virtual paths

Use cases might be too short of a password or email_confirm not being equal to email (when email_confirm doesn't equal email, I'd like mongoose to report that the problem lies in email_confirm, not email).

The issue names no files or tests. Start by tracing Mongoose's validator and virtual-path handling, then determine how virtual fields should participate in validation and error attribution; done means validators support cases such as short passwords and report a mismatch against email_confirm rather than email.
