適用范圍：When a structured document is interchanged between an originator and a recipient, the recipient refers to the stylespecifications that the originator provides to reconstruct the presentation. However, when the recipient does ncthave sufficient rendering functionality, it may fail to reconstruct the presentalion output as the originator expected.In order to preserve presentation output in the course of interchange, the originator and recipient need to negotiateover functionalities referring to the specifications of document rendering systems To satisfy this requirement, thisstandard provides the minimum requirements for specifying document rendering systems The documentspecification format shall have the same minimum requirements described hereThis International Standard can apply to the document processing environment, where a document is given in alogically structured format which is expressed by a structure markup language, and the visual representation of lhedocument is described by means of the external style and layout specifications which a style and layoutspecifications language provides. The visual representation of the given document is generated when the style andlayout specifications are applied to the logical structure by a document rendering system.This International Standard provides an abstract list of the features that a rendering system for an authoreddocument may have, The list provides a frame of reference, against which/he user and implementar can comparethe features of document rendering systems. However, this International Standard does not specify a concreteinterchange syntax or direct how each document rendering system shall behave.This International Standard provides the minimum requirements to specify the features that a document renderingsystem which transforms formatting objects to rendering output. It may be used as a frame of reference, againstwhich the user, implementer, or software agent may compare the features of a document rendering system.According to these requirements, the user may express what he or she expects of a document rendering system,the implementer may describe the functionality and capability of the document rendering system that he or sheimplements, and the software agent may negotiate a minimum set ef functionality and capability that are sharedacross different document rendering system implementations.
