This markup language was designed for GtkLabel - we are not making
GtkLabel an HTML widget. ;-)

The motivation is given very simply in the markup docs, which is that
you have to change the position and possibly nature of the text
attributes when you translate a string; so it has to be encoded in the
string to translate. That is, saying:
   set_bold (string, start_index, end_index)
would hardcode facts about the English string. So the only good way we
could think of to support text attributes on substrings is to use a
markup language, so the attributes get translated with the string.

It's obviously possible to support a more elaborate markup with tables
and so on as well, but that should probably be a separate feature.
Whether to use HTML depends on what it's used for.
