什么是SGML？
SGMLstands for Standard Generalized Markup Language. It is a standard for defining markup languages. HTML is based on SGML. It is not in itself a document language. It is a description of how to specify the document. Therefore, it is a metadata. SGML was originally designed to share machine readable large projects in government and other industries. An SGML document consists of three sections. There is a declaration. The prologue contains the DOCTYPE declaration with other markup declarations. Then the instance itself. It contains one top most element and its content.
Main advantages of SGML are it can be created by considering the document structure than thinking about the appearance characteristics. They will be more portable because an SGML compiler can interpret any document by reference to its document type definition (DTD). Documents originally intended for the print medium can easily be re-adapted for other media, such as the computer display screen.
SGML是指定数字文档类型和内容的描述的国际标准。SGML的一个缺点是它不支持样式表。由于SGML的强大设置，该软件变得未开发。除此之外，数据互换在SGML中也很复杂。
