actually that is not the philosophy. the philosophy is to make that as
close to reality as possible, and i think wicket comes very damn
close, at least a lot closer then any other.
of course when you are going to start mapping things to wicket
components that have no equivalent in html, like wicket repeaters, you
will have a bit of a mismatch.
on the other hand
<div>Product</div>
and <div><span>Product</span></div>
are virtually identical, so there isnt a huge issue adding an extra
span to represent the label
besides, your usecase is almost designed to demonstrate the "flaw",
how would you expect to map something like this:
<div id="product">Product Name ($Price)</div> ?
