A Document Type Definition (DTD for short) is a set of declarations that conform to a particular markup syntax and that describe a class, or "type", of SGML or XML documents, in terms of constraints on the structure of those documents.
A DTD may also declare default attribute values, named entities and their replacement text, and other constructs that are not always required to establish document structure, but that may affect the interpretation of some documents.
A DTD is associated with a particular document via a Document Type Declaration, which is a bit of markup that appears near the start of the associated document.
A descrition of this DTD is given here.In order to use this dtd a copy of the 'poemfrag' dtd must be in the same folder.
No narrative descrition of this DTD is available at present, but it has the same general structure as the other DTD's.In order to use this dtd a copy of the 'playfrag' dtd must be in the same folder.
DTD's and Schemas can be used to impose an order on a document, and this is exactly what we want to do at the top level of the document, where we want to make sure all the markup blurbs and e-text blurbs are included.
