Oliver Lietz commented on SLING-4443:
-------------------------------------
[~joerghoh], [~kwin], Do you have a use/test case which I could use to start
investigating what is already supported by Thymeleaf, FreeMarker and Groovy?
Do we want to enable it for single components or the complete HTML output
(which is not necessarily a complete HTML page)?
