Detail Voluntary Product Accessibility Template

Criteria Supporting Features Remarks and Explanations
(a) When software is designed to run on a system that has a keyboard, product functions shall be executable from a keyboard where the function itself or the result of performing a function can be discerned textually. Supported with exceptions:

The product has a web-based interface and some functions cannot be executed from a keyboard.

(b) Applications shall not disrupt or disable activated features of other products that are identified as accessibility features, where those features are developed and documented according to industry standards. Applications also shall not disrupt or disable activated features of any operating system that are identified as accessibility features where the application programming interface for those accessibility features has been documented by the manufacturer of the operating system and is available to the product developer. Supported with minor exceptions:

The product is browser-based; therefore the browser that is used will determine how well the application interacts with other applications.

Internet Explorer supports Windows Accessibility features and additional features that make Internet Explorer more accessible for people with disabilities. Firefox and Google Chrome also support features that make them more accessible for people with disabilities.
(c) A well-defined on-screen indication of the current focus shall be provided that moves among interactive interface elements as the input focus changes. The focus shall be programmatically exposed so that Assistive Technology can track focus and focus changes. Supported with minor exceptions. Focus, as provided through the HTML5 user interface, is dependent on the browser used to render each web page in the application. Assistive Technology can be used with a supported web browser to track focus and focus changes.
(d) Sufficient information about a user interface element including the identity, operation and state of the element shall be available to Assistive Technology. When an image represents a program element, the information conveyed by the image must also be available in text. Supported.

The product does not include animation.

(i) Color coding shall not be used as the only means of conveying information, indicating an action, prompting a response, or distinguishing a visual element. Supported:

Text accompanies color coding for critical information such as rating levels.

Color coding is used to aid in identifying some critical functions, but this is used as an enhancement and is not the only means to identify the information.
(j) When a product permits a user to adjust color and contrast settings, a variety of color selections capable of producing a range of contrast levels shall be provided. Not applicable:

This functionality is not permitted to the user.

(k) Software shall not use flashing or blinking text, objects, or other elements having a flash or blink frequency greater than 2 Hz and lower than 55 Hz. Not applicable:

The product does not include the use of flashing or blinking text, objects or other elements.

(l) When electronic forms are used, the form shall allow people using Assistive Technology to access the information, field elements, and functionality required for completion and submission of the form, including all directions and cues. Supported:

Criteria Supporting Features Remarks and Explanations
(a) A text equivalent for every non-text element shall be provided (e.g., via “alt”, “longdesc”, or in element content). Supported with exceptions . A description property is available that has not yet been fully implemented. Future product releases will continue to expand on our focus and functionality with adaptive technologies, including but not limited to Assistive Technology.
(b) Equivalent alternatives for any multimedia presentation shall be synchronized with the presentation. Not applicable.
(c) Web pages shall be designed so that all information conveyed with color is also available without color, for example from context or markup. Supported with minor exceptions:

The disposition schedule planning is color coded to aid in identifying some critical functions, but this is used as an enhancement, not the only means to identify the information. All information can be displayed accurately without color.

(f) Client-side image maps shall be provided instead of server-side image maps except where the regions cannot be defined with an available geometric shape. Not applicable:

The applications do not include the use of client-side image maps.

(g) Row and column headers shall be identified for data tables. Not applicable:

The tool used to develop the application does not make use of tables, hence row and column headers do not exist.

(h) Markup shall be used to associate data cells and header cells for data tables that have two or more logical levels of row or column headers. Not applicable:

The tool used to develop the application does not make use of tables, hence row and column headers do not exist.

The content of the text-only page shall be updated whenever the primary page changes. Not applicable:

All pages in the product are generated using HTML5. Text-only pages are not provided because the application either supports the other provisions of this part, or specific parts are not applicable to the application.

(l) When pages utilize scripting languages to display content, or to create interface elements, the information provided by the script shall be identified with functional text that can be read by Assistive Technology. Supported with minor exceptions:

Scripts are only used to provide a file transfer dialog for non-IE browsers.

Some product functions may not work properly with scripts turned off.
(m) When a web page requires that an applet, plug-in or other application be present on the client system to interpret page content, the page must provide a link to a plug-in or applet that complies with §1194.21(a) through (l). Supported:

A plug-in is required to interpret page content. The main page of the application provides a link to the plugin if it is not installed.
