As mentioned in the highlights from the June 13 telecon, Gregg and I have been working on a new checkpoint for Guideline 1 that focuses on providing information needed for unambiguous decoding of the characters and words in content. The proposed new checkpoint is included below. It is an attempt to address the issue of missing vowel marks (such as in Hebrew) and to incorporate ideas from recent discussions related to character set remapping. The new checkpoint includes many of the success criteria and ideas already captured in checkpoint 4.4 (Identify the primary natural language of text and text equivalents and all changes in natural language). Therefore, our suggestion is that checkpoint 4.4 be removed if this new checkpoint is accepted by the group. Issues: 1. The phrasing of success criteria 1 at the minimum level (maps back to) still seems a bit awkward, but we haven't been able to come up with anything better. 2. The question of what we mean when we refer to text in WCAG and how to / where to define it for the document remains an issue. [begin proposed checkpoint 1.5] Checkpoint 1.5 Provide information needed for unambiguous decoding of the characters and words in the content. Success criteria You will have successfully met Checkpoint 1.5 at the Minimum Level if: 1. text in the content maps back to the [xyz] character set (where xyz is whatever character set the international group recommends) You will have successfully met Checkpoint 1.5 at Level 2 if: 1. passages or fragments of text occurring within the content that are written in a language other than the primary natural language of the content as a whole, are identified, including specification of the language of the passage or fragment. 2. abbreviations and acronyms are clearly identified where they occur. [See also checkpoint 4.3] You will have successfully met Checkpoint 1.5 at Level 3 if: 1. the primary natural language of the content is identified at the page level. The following are additional ideas for enhancing a site along this particular dimension: • (Presently no additional criteria for this level.) Note: This checkpoint addresses the need for authors to provide sufficient information so that text can be identified correctly by technologies used to render the text (e.g. voice synthesizers) so that the words can be accurately produced and perceived. This checkpoint does not deal with providing definitions or expanded text for words, abbreviations, foreign phrases etc. These are covered under checkpoint 4.3 since they deal with understanding of the content. Definitions (informative) Natural languages are those used by humans to communicate, including spoken, written, and signed languages. Benefits (informative) Phrases from various languages, acronyms and abbreviations are often interspersed in writing. When these phrases are identified, a speech synthesizer can voice text with the appropriate accent and pronunciation. When they are not identified, the speech synthesizer will use the default accent and pronunciation of the language on the rest of the page, which can make the phrase unintelligible. Identifying changes in language and marking abbreviations and acronyms as such will also allow a tool to ask for automatic translations of that content. When editing content, authoring tools can switch between appropriate spelling dictionaries. Examples (informative) • Example 1: a French phrase in an English sentence. In the following sentence, "And with a certain je ne sais quoi, she entered both the room, and his life, forever." the French phrase "je ne sais quoi" is marked as French. Depending on the markup language, English may either be marked as the language for the entire document except where specified, or marked at the paragraph level. • Example 2: an acronym in a page title. In the following title, "RERC Information Page." the acronym "RERC" is marked as an acronym. Because it has been marked appropriately, the user agent would be able to speak the letters of the acronym one at a time rather than attempt to pronounce it as though it were a word.
