If so, then what about - ahem  - @summary? ;-)

And also, if you would like to support the workaround to use generated 
content like Charles supported, then you need to look at what happens 
if you add a border to that table. E.g. try this:

    table:before { content: attr(summary);position:absolute;left:300px }
    table {border:1px solid}

And also what happens when there already is a real <caption> in the 
table. Both those issues interferes with this - effectively - generated 
"summary caption". 

PS: If you fix these issues, then you are also preparing the ground for 
second caption ... So perhaps you should not do it ... ;-)

PPS: These things are buggy in Opera as well.
