Please review a small change to remove an inappropriate restriction on the use of '>' in HTML text. There is no such restriction in HTML 5, and it seems the same was true for HTML 4.
The check, the error message and an example for the diagnostic are all removed.
A negative test case in ElementTest.java is converted into a positive test case,
and the bug attached to that test. Some other tests needed to be updated. -- Jon JBS: https://bugs.openjdk.java.net/browse/JDK-8247788 Webrev: http://cr.openjdk.java.net/~jjg/8247788/webrev.00/
