Translation layer is an optional layer that can be added on top of a rendered page.
It has only one kind of inline element accepting only pure text content without marks, allowing one to translate text strings without changing existing markup.
Compare it with layers discussed in #3:
translation element is not actually written (?)
it is inlined
it is used only for configuring editor
it is recorded at standalone parent level ?
when doing rendering, it applies itself in a different way than other elements (it operates at string level, not at dom level, except maybe for url attributes).
