Technologies are markup languages or data formats. If the technology is a markup language, “features” refers to elements and attributes.

This test case is intended to fail because the change of user agent was not expected.
Accessibility expert.
“Rules” refer to success criteria in WCAG 2.0, checkpoints in WCAG 1.0 and similar requirements.
The test case fails the following success criterion at line 8, column 53: http://www.w3.org/TR/2006/WD-WCAG20-20060427/guidelines.html#consistent-behavior-no-extreme-changes-context.
The user initiated the change of context, but did not expect it to be connected to the user's action.
This test case maps to failure F22: Failure of SC 3.2.5 due to opening windows that are not requested by the user (http://www.w3.org/TR/2006/WD-WCAG20-TECHS-20060427/Overview.html#F22). (Example 2 for that failure says: "A user clicks on a link, and a new window appears. The original link has no associated text saying that it will open a new window.")
Note that success criterion 3.2.2, which allows certain changes of context of instructions are provided first, is not relevant here, because it applies to form controls instead of links.
The test case passes the following success criterion: http://www.w3.org/TR/2006/WD-WCAG20-20050630/#consistent-behavior-no-extreme-changes-context.
The user initiated the change of context.
The user activated the link, which initiated a change of user agent.
