Interesting, I saw that afterwards from the implementation of Element.

The main advantage of this approach is that you can modify an element
after its creation. This way you can for instance add a script to the
head element of a page after the page creation.

Using elements avoids the need to have documents like seaside ones to do
it.

This could have a HTML building time cost, since it's done in 2 steps,
but I tried to benchmark the two approaches, and I didn't see any
relevant difference.

Anyway because of how widgets are updated, the Iliad multi counter is
3-4 times faster than the seaside one :)
