National bodies that are members of ISO or IE

10、C participate in the development of International Standards through technical committees established by the respective organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, gove

11、rnmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, P

12、art 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an International Standard requires approval by at least 75 % of the nationa

13、l bodies casting a vote. In exceptional circumstances, the joint technical committee may propose the publication of a Technical Report of one of the following types: type 1, when the required support cannot be obtained for the publication of an International Standard, despite repeated efforts; type

14、2, when the subject is still under technical development or where for any other reason there is the future but not immediate possibility of an agreement on an International Standard; type 3, when the joint technical committee has collected data of a different kind from that which is normally publish

15、ed as an International Standard (“state of the art”, for example). Technical Reports of types 1 and 2 are subject to review within three years of publication, to decide whether they can be transformed into International Standards. Technical Reports of type 3 do not necessarily have to be reviewed un

16、til the data they provide are considered to be no longer valid or useful. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent rights. Amendment 1 to ISO/

17、IEC TR 19758:2003 was prepared by Joint Technical Committee ISO/IEC JTC 1, Information technology, Subcommittee SC 34, Document description and processing languages. This amendment provides additional DSSSL library specifications for basic composition styles and table compositions. ISO/IEC TR 19758:

The following procedure and Figure A1.1 show how all four margins are specified graphically using the Unwin module concept. a) Specify S point. b) Dr

23、ication of starting point The number of em characters in a line and the number of lines in a page must be specified in a content-driven specification. As shown in figure A1.2, starting point S is determined by the closest starting point on diagonal line A that will give the largest number of designa

24、ted em characters in a line between diagonal lines A and B. The following equation is used to calculate the length of the line floating direction: By adopting this equation, the graphical method can be applied to content-driven method. When using the above content-driven method as part of a DSSSL li

25、brary, specification of right margin, font size, number of lines and line spacing is required. Since the use of four sets of data is not efficient within a DSSSL library, users should limit the inputting data to values of gutter margin (*gutter-margin*) and font size (*default-font-size*). The defau

30、 Multiple strings in table cell Multiple table cell should be defined as siblings of table-cell , and have its children; row string and column string .

One restriction of this designation is that the number of columns and rows to which the diagonal is applied must be the same number. 4.18.6 Word wrapping It is possible to reduce the font size if the string in a cell is larger than the width of the cell.
