STRUCTURED DOCUMENT PREPARATION METHOD AND COMPUTER-READABLE RECORDING MEDIUM ON WHICH A STRUCTURED DOCUMENT IS RECORDED

The invention provides a structured document preparation method wherein a plurality of different logical structures can be defined with a single document type definition so that structured documents of a plurality of logical structures can be prepared and managed readily. A plurality of element declarations which respectively define a plurality of different logical structures and also a plurality of entity declarations which respectively designate the defined different logical structures are described into a document type definition, and one of the plurality of entity declarations is validated to validate a corresponding one of the plurality of element declarations. Then, a structured document is prepared with the logical structure defined by the validated element declaration.
