the DocBook Document Type DefinitionDocument Type Defintion |
|
A Document Type Definition (DTD) defines a set of elements used to create a structured (or hierarchical) document. The DTD specifies the syntax for each element and governs how and where elements can be used in a document. The DocBook 2.2.1 DTD tag set and its associated rules are referred to as formal markup. The DTD conforms to the Standard Generalized Markup Language (SGML) ISO specification 8879:1986. This means that you can use formal markup to create help files that are SGML compliant. Appendix A contains the complete DTD specification. The DTD is also available in the Developer's Toolkit. It is located in the /usr/dt/dthelp/dtdocbook/SGML directory and is named DocBook.dtd. |
