You need to change the sgml keywords in filetypes.html to add a lower-case doctype to the list (tested, it works). Probably none of those tags should be required to be only upper-case, but it would require fixing the HTML lexer from Scintilla to change that.

Refer to the user manual for information about customizing filetypes if you haven't done it before.
