HTML5不是基于SGML，因此不需要引用DTD.

HTML5 is not based on SGML, and therefore does not require a reference to a DTD.

如果不是基于SGML，HTML 5是基于什么标准的?

On what standard is HTML 5 based on if not on SGML?

推荐答案

HTML5标准指定了它具有自己完整的序列化.区别在于:HTML4具有"sgml"序列化和"xml"序列化(称为XHTML 1.0)

The HTML5 standard specifies two serializations of HTML5: "html" and "xml". "xml" is a valid XML serialization (which in turn is a subset of SGML). "html" is not based on any specific serialization standard anymore, it has its own complete serialization. Herein lies the difference: HTML4 has a "sgml" serialization and "xml" serialization (called XHTML 1.0)

当然，HTML5在很大程度上基于HTML4(基于SGML)和XHTML(基于HTML4和XML).

Of course HTML5 is for a large part based on HTML4 (based on SGML) and XHTML (based on HTML4 and XML).
