Foreword
ISO (the International Organization 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 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
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, 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 International Standard requires approval by at least 75 % of the national bodies casting a vote.
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 2 to ISO/IEC 10179:1996 was prepared by Joint Technical Committee ISO/IEC JTC 1,
Information technology, Subcommittee SC 34, Document description and processing languages.

AMENDMENT 2:
Extensions to multilingual and complicated document styles
Replace “ISO 639:1988 Code for the representation of names of languages.” of 3 Normative References with:
ISO 639-1:2002, Codes for the representation of names of languages — Part 1: Alpha-2 code.
ISO 639-2:1998, Codes for the representation of names of languages — Part 2: Alpha-3 code.
Add the following list items after the list item of “— may-violate-keep-after?” of 12.6.2 Display-group Flow
Object Class:
— ext-line-number: is a style object specifying characteristic to be assigned to ext-line-number to
determine the style of a line 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 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 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.
When layout is 3 columns, using ‘column-set-sequence’, to display the line number on both sides of 2nd
column, specify "3 4" as the value of characteristic. This characteristic is inherited.
— ext-line-number-interval: is a positive integer that specifies the interval between successive line
numbers. The default value is specified using declare-characteristic. This characteristic is inherited.
— ext-line-number-sep: is a length specifying the separation between line-number and display area. The
default value is specified using declare-characteristic. This characteristic is inherited.
— ext-line-number-side: is one of the symbols start, end, or both. Specifies the position of display area
in which the line-number is displayed. This characteristic is overlaps with ext-line-number-position:
when both characteristics are specified, ext-line-number-position has a priority. The default value is
specified using declare-characteristics. This characteristic is inherited.
— candidate-point-y: is a length specifying the candidate point of y-coordinate in a display-group region.
The default value is 0pt. This characteristic is not inherited.
— keep-with-next-table-row-count: is a number that specifies the number of table rows that are to be
kept together within the area produced by flow object when keep-with-next? is #t. The default value is 0.
This characteristic is not inherited.
— keep-with-next-line-count: is a number that specifies the number of lines to be kept together within the
area produced by a flow object when keep-with-next? is #t. The default value is 0. This characteristic is not
inherited.

keep-with-next, keep-with-previous are processed. This characteristic is not inherited when a default
value has been specified.

generated area. The default value is #f. This characteristic is not inherited.

not. This characteristic is mainly used when display FOC specifies quadding as justify and the stylesheet writer
does not expect single lines to be justified. The default value is #f.
— open-paren-space-length: is a length specifying the distance between line head and an open
parenthesis. The default value is 0pt.
— first-line-open-paren-space-length: is a length specifying the distance between the start position of
the first line of paragraph and an open parenthesis.
— continuous-number-base-position?: is a boolean indicating whether basic positioning methods based
on continuous number is to be applied or not. The default value is false.

not. When the value is #t and a line has space for justification, space can be inserted between each letter. The

in the last line of the text area. The default value is #f.
— font-height: is a length specifying height of a font using a numeric expression. The default value is 0pt.
This characteristic is not inherited.
— font-width: is a length specifying width of a font using a numeric expression. The default value is 0pt. This
characteristic is not inherited.
— font-family-name: is either #f, indicating that any font family is acceptable, a string giving the font family
name property of the desired font resource, or a list of (Language font-family-name) to specify multiple fonts.
The initial value is isoserif
— character-rotation: is one of the symbols 0, 90, 180, or 270. Specifies that floating direction on
specified inline characters. 0 means floating direction is same as the value of writing-mode. 90 means specified
characters' floating direction is orthogonal to writing-mode. The default value is 0.
— base-line-shift: is a length specifying the distance from the base line. When the value is negative, base
line is shifted up (or right). Base line is shifted down (or left) in response to a positive value. The default value is
0.
