correct use of tfoot

Hi all,

I am trying to establish the correct use (including real examples) of <tfoot>. I searched the forum and found this thread

http://lists.w3.org/Archives/Public/w3c-wai-ig/2003JanMar/0849

In the example used, the content of the cells in the tfoot are the same as the cells in the thead. Through the thread there are comments that the tfoot cells should also be <th> for that example and another reply indicates the tfoot content should be subtotals or

<tfoots> generally contain some sort of summary information (e.g subtotals
and totals) about the entire row, and it is hence beneficial to be able to
get that information while waiting for the rest of the table to load
(especially if that information is all you need from the table and you can
then stop the download).

Here are my questions:-
1. Is the initial example accurate i.e a repeat of the thead cells (assuming the size of the table warrants it)
2. If there was a general footnote relating to the table data, e.g "The charge will be refunded if the item is return undamaged" or the footnote was relating to a specific cell or column rate e.g *free delivery if purchased before 01/12/2006 
3. Does anyone have any good real-life examples I could look at

Thanks

Antony
