DTD is short for Document Type Definitions
DTD specify the rules that apply to the markup of documents of a particular type, including a set of element and entity declarations.
An XHTML DTD describes in precise, computer-readable language, the allowed syntax and grammar of XHTML markup.

php, asp(vb), jsp(java) 是server script，由server執行，html同xhtml是client script，由browser來執行，兩者是没有衝突的。server script可以output html code，只要html 符合xhtml syntax 便没有問題。
