Created attachment 599 [details] Adds a comment on "document end in prolog" errors. When the validator gets an empty document, the error message will be: > Line 1, Column 0: end of document in prolog. which is a little obscure. Since I assume that a non-empty document can actually end in the prolog, I suggest adding the following hint: > This error is often caused by an empty document. without changing the error message itself.
error explanation was added a little while ago. Forgot to close this bug.
