>It requires less work. Thats why we're seeing pushes towards XML and its applications (XHTML, WML, ect.) as opposed to HTML on low end devices, like cell phones, PDAs, and other embedded platforms. THe strictness of the langauge eases tasks when processor power, storage, and battery useage are factors that can make or break an application.

And the compiler was litle more faster (and probably to write) when it does not have to deal whit case sensitivity...
