Snippet is gone (well we forgot to remove it from the .exsd). The
fragment system is not restricted and you can contribute to nearly
everything.

To programmatically contribute to the model because there are situations
you can't contribute through a fragment because the whole thing is
completely dynamic (e.g. the simple-ide creates a Menu with all
available themes to switch).
The testsuite as well as the simple-ide have examples for it.

They are used by the change tracking system to identify an element and
when reloading from a previous restored session
