Typo3 - Enable microdata attributes itemprop, itemscope and itemtype in RTE

[veera211]

To enable microdata in RTE i think i have to add the attributes for each tag in RTE config in the root pages TSconfig.There are many examples, how to add a attribute for a tag, e.g. xml:lang:\[code\]RTE.default.proc { entryHTMLparser_db = 1 entryHTMLparser_db.allowTags < RTE.default.proc.allowTags entryHTMLparser_db.tags.div.allowedAttribs = xml:lang} \[/code\]This works very fine.But when i try to adopt this for itemprop, itemscope and itemtype:\[code\]RTE.default.proc { entryHTMLparser_db = 1 entryHTMLparser_db.allowTags < RTE.default.proc.allowTags entryHTMLparser_db.tags.div.allowedAttribs = itemprop, itemscope, itemtype} \[/code\]it's not working.Does somebody know how to add microdata attributes in RTE?
