Thats a possible solution, but you still have to consider that tables
not following these rules can not be matched this way. In this scenario
the 'tt_news' extension would fail, which could be prevented by matching
against the prefix 'tt_' in addition.

Anyway, I was just wondering if there is some informationen about the
relation of tables and plugins I can rely on.

Thanks so far.
