8、for Standardization) and IEC (the International Electrotechnical Commission) form the specialized system for worldwide standardization. National bodies that are members of ISO or IEC participate in the development of International Standards through technical committees established by the respective

9、organization to deal with particular fields of technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the work. In the field of information tec

10、hnology, 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, Part 2. The main task of the joint technical committee is to prepare International Standards. Draft International Standa

11、rds 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 national bodies casting a vote. In exceptional circumstances, the joint technical committee may propose the publication of a T

12、echnical 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 2, when the subject is still under technical development or where for any other reason there is the future but not imme

13、diate 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 published as an International Standard (“state of the art”, for example). Technical Reports of types 1 and 2 are subject to re

14、view 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 Technical Reports of type 3 do not necessarily have to be reviewed until the data they provide are considered to be no longer valid or useful. Attention is drawn to the possibility that so

18、sed on the Unwin module concept. 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) Draw diagonal line from the top-right edge through S point to bottom left edge. c) Draw line from left page of bottom-le

19、ft edge to right page of top-right edge. d) Draw line from left page of top-left edge to right page of bottom-right edge. e) Draw line from left page of top-left edge to left page of bottom right edge. f) Draw line from right page of top-left edge to right page of bottom right edge. g) Draw horizont

Figure A1.2 Specification of starting point The number of em characters in a line and the number of lines in a page

22、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 designated em characters in a line between diagonal lines A and B. The following equation is used to calc

23、ulate 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 library, specification of right margin, font size, number of lines and line spacing is required. Sin

24、ce 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 default value of line-spacing is designated as 1.5 em. ” Page 14, Clause 4.18 Add the following clauses

25、 after 4.18.2: “ 4.18.3 Rounded corner table The shape of a table is rectangular, though corners are allowed to be rounded. If you wish to round the corner of table, use *corner-rounded-table-style* under the specification of element table. The radius of the corner is specified using (define *base-t

26、able-corner-radius* 3pt). By changing the number within define, the radius of table corner is specified as the value of it. The default value of a table corner radius is 3pt. Diagonal Line A Diagonal Line B length of line direction = (number of line -1) (line spacing) + (character size) ISO/IEC TR 1

The table header column and table header row should have the

28、 same children as table column and table row respectively, and initially be specified with their background color of light-gray, as shown in figure A1.3. 4.18.5 Multiple strings in table cells Figure A1.4 Multiple strings in table cell Multiple table cell should be defined as siblings of table-cell

29、, and have its children; row string and column string . The row string includes #PCDATA which are related to row data. The column string includes #PCDATA which are related to column data.

One restriction of this designation is that the number of columns and rows to which the dia

31、gonal 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. This is designated using the attribute DesFSize=”#t”, which indicated that the font size is to be reduced if the cell width is exceeded.
