Re: [html5alt] some thoughts on LEGEND

not sure I follow this.

I though legend was intended to bind a caption that appears below a  
picture with the picture.  Not create a way to attach metadata to a  
group.

Also I thought that we decided the three stages of a butterfly  
required alt on each of the items.  The legend was used only to put a  
caption on the group.

Using it for non-visual binding and description of groups would not  
seem to make sense.   if the group was a group, then all readers would  
need to see it.  no?


Maybe I'm missing your point.   What other places did you think of  
using it?
