9、orldwide standardization. National bodies that are members of ISO or IEC 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 collaborat
10、e 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 technology, ISO and IEC have established a joint technical committee, ISO/IEC JTC 1. International Standards are
11、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 Standards adopted by the joint technical committee are circulated to national bodies for voting. Publication as an I
12、nternational Standard requires approval by at least 75 % of the national bodies casting a vote.

16、number. ext-line-number-start: is a number that start point of sequence of line numbers to be output. The default value is specified using declare-characteristic. This characteristic is inherited. ext-line-number-position: is either #f or a string that specifies the position within the display area
17、at which to output the line number. The default value is specified using declare characteristic. The string property specifies the position of the number by counting from either side of the display area from the initial position of the writing-mode. Thus, when the writing-mode is left-to-right with
18、a layout of simple-page-sequence, specifying the value as “2” will display line-number on the right-hand side of the main text area.
