There are three or four kinds of notes, which need different
treatment:

* Design notes of the writeup format, cf Vehicles Lite. Those
  are part of the writeup itself.
* Rules notes, not part of any official format, to clarify 
  which rules sets and errata versions were used. Again, I 
  consider those part of the writeup itself.
* Writer's notes, like "another one for John Doe's game." If 
  a writer wants them in, we should respect that and make 
  them part of any rendering. Could be a disclaimer or the 
  like, not fair to dump that optionally. 
* Notes by others, like the GM of a game. I'm terribly uneasy
  about those - I want to control what goes out with my name 
  on it.

> remove <week> add the week number to the bottom <notes>

For v.o.t.w., week is a key metadatum.

> <date> needs to be broken up into <day>, <month> and <year>

Or clarify that is follows iso 8601. OTOH, that is the W3C 
standard, so it could be the default.

> <copyright> for the copyright notice

How we render that depends on the medium. It could well be
the circled c rather than "all rights reserved".

> <email> for email address of author

Nope. These days, publishing email is an invitation to spam.
Besides, for lots of writers I don't have current addresses.

If it is not interpreted as text field, we should also 
make it length/width/height.

> <aspeed measurement="USmph">2,360</aspeed>

In that case, it should be 

<aspeed measurement="mph">2360</aspeed>

to make it a genuine number. Except that I can't think
of anything other than (US or international) mph in that 
field, so the attribute is rather pointless.
