Because of some CSS & (X)HTML I want to add doctype ""http://www.w3.org/TR/REC-html40/loose.dtd" to "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">. can I add this to my pages that it automatically generate "<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd"> or do I have to add it manually ?
