The problems only start when you are in a context where
wrapping elements are not allowed (by the DTD/Schema).
An example is the "select/options" context.
Maybe more relevant: using "tbody" to repeat table rows.
"tbody" has specific semantics which may not be compatible
with the ZPT use (e.g. I may need larger groups, but
"tbody" cannot be nested).

The new "tal:whatever" pseudo elements help in this direction
(they disappear after rendering leaving only the content).
But in a strict environment, they make the template itself
non-conformant and difficult to check against a DTD/Schema.

Thus, I would prefer not to be forced to use artificial wrapping
elements.

I do not have a proposal, though....
