Technologies are markup languages or data formats. If the technology is a markup language, “features” refers to elements and attributes.
The test is intended to pass because the luminosity contrast ratio is higher than 10.
The formula to be used for calculating the luminosity contrast ratio can be found at http://www.w3.org/TR/2006/WD-WCAG20-20060427/appendixA.html#luminosity-contrastdef.
“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case passes the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#visual-audio-contrast-contrast.
The foreground and background colours have enough contrast.
The luminosity contrast ratio is 11.20.
The test case needs review before it can be established if it passes or fails the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20050630/#visual-audio-contrast-contrast.
The WCAG WG hasn't provided threshold values for colour contrast yet.
