[TYPO3-english] displayCond on flexforms

[Sergio]

Hi,

I've been using <displayCond> for my flexforms for a while, and now I have
some special cases and I wondered:

1) Can I use this condition to express "the releaseYear is not empty"?:

<displayCond>FIELD:settings.releaseYear:!=:</displayCond>

2) Is there a way to use conjunction conditions like

<displayCond>FIELD:settings.releaseYear IN (2012, 2011, 2010)</displayCond>

Something like that...

Thanks in advance,
Sergio
