Scope and Field of Application This Technical Report complements IS0 8879 by providing additional turorial information. It is not intended@ and should not be regarded@ as an extention@ modification@ or interpretation of IS0 8879. The SGML language contains a number of components@ some of which are optional features. The tutorial information covers the main components of the language only; notably a discussion of LINK@ CONCUR@ and DATATAG is outside the scope of this Technical Report. The intended audience is mainly document type designers already familiar with the basic concepts of SGML@ but requiring more tutorial information on techniques for using SGML for various applications. Subclauses 5.3 and 8.4 are written in the style of a ??User Guide?? and can be used as a basis for end-user documentation. For an introductory tutorial on SGML the annexes of IS0 8879 can be used. This Technical Report includes notes on the analysis of a document prior to the writing of a formal document type definition@ and a series of examples. The principal example is for a general document type@ formally defined as an example in clause E.l of IS0 8879. Others of a general nature are for letter and memorandum@ spreadsheet@ mathematics@ and the mixing of text and graphics. Those for language applications include Scandinavian runes@ Japanese@ a European multilingual document@ and mixing text in languages written from left to right and from right to left. NOTE - Throughout this Technical Report terms like ??is keyed in??@ and ??with keyboarding?? are Used. This does not neccessarily imply that the markup is to be added explicitly by a user; for text entry one would expect structured@ context sensitive@ editors to be used@ or the markup added by application programs@ e.g. in tM case of interchange of spreadsheets.
