Missed that. Thank you.

XHTML5?

Maybe for my next *major* update.

Ooops!

Thats why it is marked "s" = "sometimes".

I thought it just moved to a separate spec?

OK. I just took for granted that it would include all ruby markup from 
XHTML 1.1. And that the rest just wasn't spec'd yet. Has this been 
discussed? Where?

(I have not got time to follow every conversation, so sometimes I miss 
stuff. That's why I am asking for help ;-) )

Yes. Since my last revision it is.

Will fix.

Will fix.

Perhaps I should be more clear about what I mean with "blockish"...

This table is goes back more than a few years and is the result of 
talking to my students. It is based on my personal quick way of 
explaining this to complete newbies:

1. Block elements will cause line breaks and must be floated or 
positioned in order to have contents on their sides.

2. Inline elements may never contain block elements.

Both rules apply to table.

Anyway, I think it is probably wise to be more precise. I will change 
it. Today I also teach CSS from day one, making it more clear what I 
mean anyway.

I thought they were ignored completely...? At least they should be, IMHO.

Ooops!

Weird indeed, but an input control will be shown. Sounds replaced to me!

Anyone who can conform this?

Anyone who can conform this?

I thought some control would be shown. in my rightmost column I have 
said tha "Button, radiobutton or checkbox" will be shown.

That was deduction from my part. How else would they display if not 
through some widget?

You mean, usually "R", but "N" when providing text-fallback?

Sounds like it's too complex to describe with just one letter...

As indeed it is in my table.

Sounds reasonable. Will change.

A quick test proves this to be the case.

It is a very fragile technique that requires fixed widths for table 
columns and is almost impossible to get pixel perfect right.

I think it is a very clear use case for something that should be very 
easy to accomplish in CSS, and I have sent an e-mail to the CSS WG. So 
far I have received no answer from anyone, though.
