Hello,  
I use the Datetime field in my current project. I have seen, if I select  "no date/time picker", I obtain a standard HTML Inputfield. 
Is it possible to obtain a HTML5 Inputfield for date instead of a HTML? 
That is: 
I obtain <input type="text"  instead of  <input type="data" ... 
It would be usefull an option to select the output format in order to make native HTML5 pages. 
What code should I change to do it ? 
Thanks in advance.
