30、reword IS0 (the International Organization for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for world-wide standardization. National bodies that are members of IS0 or IEC participate in the development of International Standards through technic
31、al committees established by the respective organization to deal with particular fields of technical activity. IS0 and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with IS0 and IEC, also take part
32、in the work. In the field of information technology, IS0 and IEC have established a joint technical committee, ISO/IEC JTC 1. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approva
33、l by at least 75 % of the national bodies casting a vote. International Standard lSO/lEC 10538 was prepared by Joint Technical Committee ISO/lEC JTC 1, Information technology. Annexes A, B and C of this International Standard are for information only. vii Copyright American National Standards Instit

35、 in Draft International Standard ISO/DlS 6937-3 (for the control functions for page-image format), and in the Draft Proposal for IS0 6937-4 (for the control functions for formatted and formattable text). Because these repertoires of control functions are applicable to text communication in general,
36、and can be used independently from IS0 6937, JTC l/SC2 at its 21st plenary meeting in London in October 1988 decided in resolution 8 that the former IS0 6937-3 and IS0 6937-4 were to be published as a single new International Standard. . . .

38、trol functions, and their coded representations needed. for use in text communication. Section 2 specifies the control functions for text in page-image format, Section 3 specifies the control functions for formatted and formattable text. The controi functions, with the exception of two, have been ta
39、ken from IS0 6429. The definitions of the control functions in this International Standard are, in general, more specific than the corresponding definitions in IS0 6429. The specifications in this International Standard apply to the interchange of text in the form of binary-coded representations of
40、graphic characters and control functions. They are not intended for the actual processing of text. Although, in general, text consists of characters and pictures, this International Standard applies only to text made up of characters. The coded representations defined in this International Standard
41、are intended for use when the control functions concerned are embedded in the communicated text, not when they are separated from the text as elements of a communication protocol, for example. This International Standard does not define any control functions required for controlling the process of c
42、ommunication. 2 Conformance 2.1 Types of conformance Full conformance to a standard means that all of its requirements are met. Conformance will only have a unique meaning if the standard contains no options. If there are options within the standard then they shall be clearly identified, and any cla
43、im of conformance shall include a statement that identifies those options that have been adopted. This International Standard is of a different nature since it specifies for the applications in Section 2 and Section 3 a number of facilities from which different selections may be made to suit individ
44、ual application requirements. These selections are identified as levels in clauses 12 and 16. They shall be identified at the time that a claim of conformance is made. Conformance to such an identified selection is known as limited conformance. 2.2 Conformance of information interchange A coded-char
45、acter-data-element (CC-data-element) within coded information for interchange is in conformance with a Section and a level of this International Standard if all coded representations of control functions within that CC-data-element conform either to the requirements of clause 12 or to those of claus
46、e 16. A claim of conformance shall identify the Section and the level adopted.

47、 device is in conformance with this International Standard if it conforms to the requirements of 2.3.1, and either or both 2.3.2 and 2.3.3. Any claim of conformance shall identify the document which contains the description specified in 2.3.1, and shall identify Section and the level as well as the
48、selected control functions. 2.3.1 Device description A device that conforms to this International Standard shall be the subject of a description that identifies the means by which the user may supply the selected control functions or may recognize them when they are made available to him, as specifi
49、ed in 2.3.2. and 2.3.3, respectively. 2.3.2 Originating devices An originating device shall allow its user to supply any sequence of control functions from the Section and level adopted, and shall be capable of transmitting their coded representation within a CC-data-element. 2.3.3 Receiving devices A receiving device shall be capable of receiving and interpreting any coded representations of control funct
