Is case sensitivity necessary with <!DOCTYPE html> ?

On various occasions I've seen instructors use it in both upper and lowercase. I'm just curious as to which is the correct one.

no HTML 5 is not casesenzitive however some people think if you write it in lovercase your code is wrong but they are wrong your code is OKEY :)

but in XML serializations you should use UPPERCASE
