Joomla content editor strips the <meta /> tag about plg_system_structureddata

[betweenbrain]

Does it strip an empty meta tag like <meta /> If so, maybe this be added to the default whitelist of filters.

Yes, that could solve the problem, but if it is inserted in the Blacklist there is a reason? security reason?
I can't find that list in the Joomla project...

[betweenbrain]

I'd need to review the code to be sure, but I don't think it's necessarily a case of it being in the blacklist per se, but more of a case of only those tags in the whitelist being allowed. I think if it isn't in the whitelist, it may be filtered out by default.

But, Super Users aren't filtered by default, so it this may also be a TinyMCE issue too.

I think, from memory, that only tags on a whitelist are allowed. May be worth adding meta to the whitelist if we can? Does this help? http://www.tinymce.com/wiki.php/configuration:valid_elements

@RCheesley Yes that helps 👍
In Joomla the default tinymce blacklist is: invalid_elements : "script,applet,iframe", as you see there is no meta tag included in that list, tinymce strip it anyway.

Great, so there is a workaround at least - are we able to change that setting to have the meta tag whitelisted?
