[TYPO3-dam] DAM References

Hi,

This field is never written to directly. If you look at its TCA, it's a 
user-defined field and calls on 
EXT:dam/lib/class.tx_dam_tcefunc.php:&tx_dam_tceFunc->tx_dam_fileUsage, 
which itself queries the tx_dam_mm_ref table and renders the table of 
related records.

Cheers
