[TYPO3-mvc] RFC: New comments in FLUID

[Michael Knoll]

Hi,

I'm not really sure about that - but I always thought, that FLUID 
templates ARE NOT WELL FORMED. At least namespace definitions in FLUID like

{namespace extlist=Tx_PtExtlist_ViewHelpers}

are not well-formed - or am I wrong?

Besides, <!--- ---> could easily be changed in something like #
<!--. .--> if that should really be the problem.

I guess most IDEs check for <!--.+?--> as being a comment, so it does 
not matter what browsers etc. take as well-formed, as there won't be any 
usage of this in browsers.

So where do you think this could be a problem? FLUID templates are not 
well formed and are not HTML5 compliant - as far as I see.
