[TYPO3-english] TCA/IRRE: limit possible "type" of related child records in "inline" fields?

[Roland]

hi everybody,

i have got an custom extension with a table column of type "inline". in 
this collumn tt_content records can be added/saved via IRRE.

question: is there a possibility to limit tt_content record *types* so 
that e.g. only tt_records types "header", "text" and "image" can be 
added/saved in this field?

kind regards

roland
