accessibility overview
welcome to the accessibility area of aatideas.org. AAT strives to build accessibility into each area of the web site. this document provides information about AAT's approach toward providing accessible web content.
this area is subject to further development to include the development of particular types of accessible document. a site index for aatideas.org also provides information on the location of particular documents.
comments about the accessibility of aatideas.org web documents are welcome, as AAT is continually striving to improve quality of the web site content for everyone regardless of disability. contact AAT if you would like to suggest any changes or improvements to the aatideas.org web site.
quality plan
AAT is continually striving to improve access to the aatideas.org web site. there are several aatideas.org projects however. the incorporation of planned accommodations may take some time. in the meantime, many pages are subject to content and web-address updates.
this web site is developed to provide web-friendly access to web site content. AAT P9001 designates a number of standards for web-site development: XML, XHTML, CSS, RSS, W3C WAI, WCAG, section 508, BITV, Unicode, aatideas.org privacy policy and code of e quality, and ICAS. the aatideas.org style guide contains additional information about the presentation of aatideas.org programming.
the datetime stamps on aatideas.org web site documents are elaborated for multiple purposes. please see the ICAS in use conformance level B area of this web site for additional information.
the web site documents may be accessed best with modern web browsers on up-to-date versions of operating systems. access via legacy configurations may not render markup correctly.
the aatideas.org web site is developed and administered by AAT programs manager Ronald L Stone with acknowledgements to many in the technical communication and www communities for strategies and methods of presentation, and to Claudia Stone for additional program support.
about the web site reorganization
aatideas.org was reorganized with xht(ml) filetyping to improve web browsing, and also to present content more accessibly to certain mobile or handheld device platforms.
many of the previously-developed web site documents that were named with an 'html' extension have been replaced with new documents that are named with a standard 'xht' extension. the new documents should display correctly with a recent- or current-version browser that can render markup coded to internet standards for XHTML and CSS.
this document is an XHTML 1.1 document with an 'html' file extension that aatideas.org has determined can be viewed by most if not all popular modern XHTML browsers. however areas of this site are expected to be built with the new 'xht' file extensions. as the more usable 'xht' file extension gains additional support, it will also be integrated into new web site documents.
most of the areas of this web site have been migrated to 'xht' filetypes. however at least 3 'html' documents are expected to be maintained indefinitely: the top www.aatideas.org/index.html page, the 'icas/index.html' page, and the accessibility information page.
browsing the new areas of this site
as web standards further develop, and as browsers further improve, this web site can be rendered best with a recent- or current-version modern XHTML and CSS-ready browser.
those using a legacy browser (pre-XHTML) can select from a growing number of XHTML browsers that can be obtained at no charge from various third-parties. visitors may wish to select a 'multi-terrain' browser for parsing XHTML and CSS documents with an 'xht' filetype. these browsers include current versions of Opera and Safari, in addition to Firefox. other popular browsers can already parse XHTML and CSS documents if they have an HTML file extension such as 'html', yet may still be due for a minor patch to render documents with an 'xht' filetype.
those preparing 'xht' web documents should also note that the web server should also be configured to serve XHTML 1.1 documents with 'xhtml' or 'xht' extensions as content-type 'application/xhtml+xml' rather than the 'text/html' content type served for legacy HTML documents (yet note that forthcoming HTML 5 specification is also expected to encompass the XML syntax of XHTML 1.1 as one particular syntax). check with W3C for further information and for important updates.
why is a filetype(xht) useful for web users and developers?
from a web usability standpoint, the 'xht' file extension can be regarded as more readily usable than the 'xhtml' file extension, because for many common user tasks a file extension of 3 characters is more readily usable than a file extension consisting of 5 characters. the common use of a standard 3-character file extension can thereby increase usability for a situation such as when using a touch type screen rather than a full-sized keyboard (or when pasting a URL).
XHTML documents do not need to run the larger legacy HTML instruction sets used by legacy HTML and thus can be rendered by modern XHTML browsers more efficiently in comparison to legacy HTML documents. XHTML 1.1 documents are moreover more interoperable with the widely-used XML standards for structuring information. This can better accommodate the porting of information from web documents to XML syndication like RSS.
CSS standards make possible a more efficient presentation of structured content in terms of dedicated style rules.
