It's useful to prevent mistakes, not just following the standard to the letter.
Given that the XML file is in an Emacs buffer there is a fair chance that it
was hand-written, and then the extra ">" is likely to be unintended, especially
since it can be somewhat hard to spot by a human.
Many other modes do similar things. For example, emacs-lisp-mode warns about
useless backslashes in strings even though there is no actual syntax error.
Think of it as a useful compiler warning.

That's fine. Dan can reopen if he thinks nxml-mode really needs improvement.
