Preamble:
- yes, I know the HTML export is currently stalled...! But maybe, while
implementing new notes, we can improve the filter a little bit in this area?
- This issue deals whith 2 different problems. Ask if you need 2 tasks :)

1) Notes creation time, date and author get lost when saved to HTML (FEATURE).
Writer "Notes" are exported as neutral comments (<!-- ... --> HTML tag) to HTML.
Everything which is not part of the note body (time, date and author) is not
exported to HTML.
-> it may be quite easy to export this information "as" note body whith special
keywords and parse this keywords when importing.

Example: A note is inserted by author Max on 29th, January 2008 at 23:00 with
body "I am a note"
The comment code could be:
<!-- %note_body="I am a note", %note_author="Max", %note_time="20080129;23000000"-->

2) The first note of an HTML document is destroyed when the document is edited
by someone else as the author (BUG).
Description:
- New HTML document
- Tools - Options - OpenOffice.org - User Data
- Type First name: "Creator", Ok
- Insert a note and type "This is a note" in it
- Save the document
- Tools - Options - OpenOffice.org - User Data
- Type First name: "Review", Ok
- Type something in the document
- Save the document
- Reload
-> the content of the note is now "HTML: <META NAME="CHANGEDBY"
CONTENT="Reviewer">" instead of "This is a note".
