Snapshot feedback

[Joe Gregorio <joe@xxxxxxxxxxxxxx>]

Here are my comments on the 2003/07/01 snapshot:
http://intertwingly.net/stories/2003/07/01/example.necho

1) feed.subtitle should be optional.

2) entry.content - I think there should be only one,
   and it should be required, and it may be empty.

3) Drop entry.author.weblog and entry.author.weblog, replace
   with a single element called entry.author.id.
   Do the same for entry.contributor.

Lastly, a clarification, if an element is noted as being
required, can it still be zero length? I ask because
entry.title is required and has a note that it may be zero
length, making me doubt that the other required elements may
be zero length.

	Thanks,
	-joe
