[TYPO3-english] microdata inside of htmlarea

[Domi]

Hello,

I want to use the htmlarea to insert predefined textstyle tags for the 
insert of microdata in my RTE. I created the class = "micro" which is 
selectable through the RTE but how can I wrap the microdata inside the span?

At the moment the microdata even gets filtered out, if I switch to the 
source code view.

Thanks for any hints how to deal with this.

Regards,
Dominic
