DTD coding requirements

This section explains how to implement DTD-based document-type shells, specializations, and element-configuration modules (constraint and expansion).

DTD: Use of entities
DITA-based DTDs use entities to implement specialization and element configuration. Therefore, an understanding of entities is critical when working with DTD-based document-type shells, vocabulary modules, or element-configuration modules (constraint and expansion).
DTD: Coding requirements for document-type shells
A DTD-based document-type shell is organized into sections. Each section contains entity declarations that follow specific coding rules.
DTD: Coding requirements for structural and element-domain modules
This topic covers general coding requirements for defining element types in both structural and element-domain vocabulary modules.
DTD: Coding requirements for structural modules
This topic covers general coding requirements for DTD-based structural modules.
DTD: Coding requirements for element-domain modules
The vocabulary modules that define element domains have an additional coding requirement. The entity declaration file must include a parameter entity for each element that the domain extends.
DTD: Coding requirements for attribute-domain modules
The vocabulary modules that define attribute domains have additional coding requirements. The module must include a parameter entity for the new attribute, which can be referenced in document-type shells, as well as a general entity that specifies the contribution to the @specializations attribute for the attribute domain.
DTD: Coding requirements for element-configuration modules
Element-configuration modules (constraint and expansion) have specific coding requirements.
