With totally broken I mean "broken in sense of kernel-doc markup".
E.g. the missing ":" at the end of "@bar.st2.arg2:" instead, there
is a minus "-". And in the first example you gave, there also missed
a ";" at the end of some of the elements. Anyway, the example
above is obsolete.

Ah, ok lets fix the example.
