th:src tags in structured content not working

[om.singh]

I have used created a structured content which has html - with th:href or th:src tag. when this is rendered on the page - it throws and exception

Error processing template: dialect prefix "th" is set as non-lenient but attribute "th:href" has not been removed during process (layout/fullPageLayout:2)

Is there some thing , which I need to do , in order to be able to use such tags in the cms content.

Just to add, this was working fine on the previous version ( one below the ga)

If I remove the th: tags from the content - it works fine. But i am here not sure , why its not getting computed , like th tags. This was though working earlier, before i upgraded to the ga release.

Any one who has used th: tags in cms content? Can you please help.
