1. Introduction
As presented in CSUN 2004 and 2005 Guidelines for older persons and persons
with disabilities —Information and communications equipment, software and
services- Part 3: Web content) was published in June 2004. After the publication
of Web Accessibility International Standards Research Working Group (WG2) was
organized at INSTAC (Information Technology Research and
2. National promotion of JIS X 8341—3
In order to promote JIS X 8341-3, WG2 prepared techniques handbook working
draft [J1S— Tech], which is open to the public on the Web. This handbook
explains specific
requirements of JIS Y 8341-3 in terms of (X)HTML and
CSS techniques.
3. International standard harmonization
3. Japanese translation of WCAG 2.0
In order to harmonize Web Content Accessibility Guidelines, two members of WC2
participate in WCAG Working Group of W3C/WAI. WC2 translated June 30
Working Draft of WCAG 2.0 [WCAC2.OWD] and some Techniques documents for WCAG
2.0, which is open to the public on the Web [WCAC2.OWD Japanese translation]
3.2 Comparison between JIS X 8341-3 and WCAG 2.0 Working Draft
In order to examine the differences between JIS X 8341—3:2004 and the current
WCAG 2.0
Working Draft, WG2 compared specific requirements of JIS X 8341—3 and success
criteria of
WCAG 2.0 Working Draft.
We found the following success criteria are not covered by JIS X 8341—3:
1) GL 1.2 Level 3 SC 1: Sign language interpretation is provided for
multimedia.
2) CL 2.4 Level 2 SC 1: More than one way is available to locate content within
a set of delivery units.
3) CL 2.4 Level 3 SC 1: When a page or other delivery unit is navigated
sequentially, elements receive focus in an order that follows relationships and
sequences in the content.
4) GL 2.5 Level 3 SC 1: Additional context—relevant assistance is available for
text input.
5) GL 3.2 Level 2 SC 3: Changing the setting of any input field does not
automatically cause a change of context.
6) CL 4.1 Level 1 SC 1: SGML-based delivery units are well-formed.
7) CL 4.2 Level 1 SC 2: Content using baseline technologies or non-baseline
technologies, must meet the following criteria:
A. Content that violates international health and safety standards for general
flash or red flash is marked in a way that the user can avoid its appearance
B. If the user can enter the content using the keyboard, then the user can exit
the content using the keyboard.
8) CL 4.2 Level 1 SC 3: The role, state, and value can be programmatically
determined for every user interface component of the web content that accepts
input from the user or
hangs dynamically in response to user input or external events.
) CL 4.2 Level Sc 5: The states and values of content that can be changed via
the user
interface can also be change programs critically.
10) CL 4.2 Level 1 SC 6: changes to content, structure, selection, focus,
attributes,
values, state, and relationships within the content can be programmatically
determined.
11) CL 4.2 Level 3 S 1: content implemented using
technologies outside of baseline
follows all WCAG requirements supported by the technology.
Some success criteria are too difficult to understand their meaning and intentions.
We also found the following requirements are not covered by WCAG 2.0 Working
Draft:
1) 5.5 b) Information required to understand and operate Web
content shall not rely on
shape and location alone.
2) Clause 6. General requirements for assurance and improvement of information
accessibility
WG2 will discuss these differences with WCAG WG in order to promote
international standard harmonization.
