Changes

* Endnote number in text: The number is the link which appears in square brackets. Square brackets themselves are not part of the link. HTML coding for the text: '''[<a nameid="ref1" href="#note1">1</a>]'''

* The link should work both ways. So, the endnote will link back to the text. HTML coding for the endnote: '''[<a hrefid="#ref1note1" namehref="note1#ref1">1</a>]'''
