[TYPO3-RTE] RTE transformations ! get rid of valign inside td tag

[Pierre Rouwens]

Hi folks,

I need a way to get rid of valign inside td tag.
A contributor has formated many tables with that. But the webmaster 
wants me to delete those.
I've searched through the documentation without any hint about how i can 
do this.
Of course i've tried many things including the RTE.default.proc tags 
management but seems like i can't act on td.

Any help would be appreciated.

Thanks

Pierre
