Specifies a set of functions which an SGML syntax-directed editing system may have in order to help users manipulate documents. Contains two major clauses. The first one describes the functions on an SGML syntax-directed editing system as applied to document processing. The second clause identifies those additional facilities felt to be appropriate for DTD processing. Does not specify a "standard editing system". Is primarily aimed at the creator of "text" documents. Although SGML can be used, for instance, for databases, spreadsheets, mathematics, and even music, these uses are not directly considered.
