How about having one caption in the markup, having a property to control
whether it repeats, and then a pseudo-class for repeated elements?

e.g.

   <table>
     <caption>Something or Other</caption>
     ...
   </table>

... some magic CSS to make caption repeat ...

caption:repeat(1+n)::after { content: " (cont.)"; }

(Can we move this discussion to www-style, btw? It wouldn't hurt to get
others' ideas.)

Hi fantasai,

 > Can I post this to www-style?

Sure.

At the moment in Prince we have implemented this property:

     prince-caption-page: first | following | all

And we use it in combination with multiple table captions.

Best regards,

Michael
