The TCA for a given table is generally split into two files:
- the "ctrl" section goes into ext_tables.php
- the rest of the TCA goes to tca.php
The point is that - most of the time - TYPO3 needs to know only about
the "ctrl" section of each table. Occasionally it needs more details, in
which case the full TCA is loaded. This is done by calling:
This checks the "dynamicConfigFile" property of the "ctrl" section and
loads the corresponding file. To make sure that the "ctrl" section is
not lost, the tca.php file contains:
$TCA['myx'] = array(
'ctrl' => $TCA['myx']['ctrl'],
I hope this explains a bit more.

It is. It's also quite powerful so hang on and you'll get it ;-)
You may want to look at existing extensions to compare the code. In
particular, there's one called "examples" which contains the code
samples corresponding to the "Core API" manual. Although it is far from
complete, it is meant to provide useful examples and code snippets to
