What about <svg:g> elements? It would be very useful to allow them there.

And <p> elements (in fact in one application where I did something like 
this once, I was repeating <p> elements).

And <tbody>, in case what is being repeated is more than just one row.

And if we're going to allow <li>, why not <dd>?

So the full list would be <fieldset>, <tr>, <tbody>, <td>, <p>, <li>, 
<dd>, and <svg:g>. Assuming we haven't missed any. (<section>?)

Now, consider the implementation. Every time it has to do anything in the 
repetition model, it will now have to check the tag name against all of 
these before deciding whether or not an element is a repetition block.

The ua.css rules go from:

   @namespace xh url(http://www.w3.org/1999/xhtml);
   xh|*[|repeat="template"] { display: none; }


   @namespace xh url(http://www.w3.org/1999/xhtml);
   @namespace svg url(http://www.w3.org/2000/svg);
   svg|g [xh|repeat="template"], xh|fieldset[|repeat="template"],
   xh|tr[|repeat="template"], xh|tbody[|repeat="template"],
   xh|td[|repeat="template"], xh|p[|repeat="template"],
   xh|li[|repeat="template"], xh|dd[|repeat="template"] {
     display: none;

I don't understand why it bugs you that template attributes apply to all 
elements, and don't understand why you think they should only apply to 
fieldsets. Could you expand on this?
