[TYPO3-core] RFC: TCA Sections

I would prefer if you made a
'parentField' => array('tx_kbnntpif_messages' => 'msgparent',
'tx_kbnntpif_message_parts' => 'partparent');
And the rest in something like 'section' => ...

So the parentField could be generally used for other tables, too. And a
tree could then be built also without any needs for TCA sections.

I do not think so. M stands for 1 - M. N:M and M:M means the same thing.
