From The Platform for Privacy Preferences 1.0 (P3P1.0) Specification (2002-04-16) | Glossary for this source
A program whose purpose is to mediate interactions with services on behalf of the user under the user's preferences. A user may have more than one user agent, and agents need not reside on the user's desktop, but any agent must be controlled by and act on behalf of only the user. The trust relationship between a user and his or her agent may be governed by constraints outside of P3P. For instance, an agent may be trusted as a part of the user's operating system or Web client, or as a part of the terms and conditions of an ISP or privacy proxy.

From Glossary of Cascading Style Sheets, level 2 CSS2 Specification (1998-05-12) | Glossary for this source

- user agent default styles
-
From User Agent Accessibility Guidelines 1.0 (2002-12-17) | Glossary for this source
User agent default styles are style property values applied in the absence of any author or user styles. Some markup languages specify a default rendering for content in that markup language; others do not. For example, XML 1.0 [XML] does not specify default styles for XML documents. HTML 4 [HTML4] does not specify default styles for HTML documents, but the CSS 2 [CSS2] specification suggests a sample default style sheet for HTML 4 based on current practice.

capabilities of the device, the operating and network environment,
and users personal preferences for receiving content and/or

- user control of every user interface component
-
From User Agent Accessibility Guidelines 1.0 (2002-12-17) | Glossary for this source
This document distinguishes user interface features that are part of the user agent user interface and those that are part of content. Some checkpoints (e.g., those in guideline 5) require user control over rendering and behavior that is driven by content only. This document does not always explicitly require the same control over features of the user agent user interface. Nevertheless, this document (see checkpoint 7.3) does require user agents to follow software usability guidelines. The UAWG expects such usability guidelines to include requirements for user control over user interface behavior.Note: It is more difficult for users to distinguish content from user interface when both are rendered as sound in one temporal dimension, than it is when both are rendered visually in two spatial dimensions. Thus, the UAWG encourages developers of user agents that include audio output or synthesized speech output to apply the requirements of this document to both content and user agent components.

From User Agent Accessibility Guidelines 1.0 (2002-12-17) | Glossary for this source
For the purposes of this document, user interface includes both: the user agent user interface, i.e., the controls (e.g., menus, buttons, prompts, and other components for input and output) and mechanisms (e.g., selection and focus) provided by the user agent ("out of the box") that are not created by content.the "content user interface," i.e., the enabled elements that are part of content, such as form controls, links, and applets. The document distinguishes them only where required for clarity. For more information, see the section on requirements for content, for user agent features, or both. The term "user interface control" refers to a component of the user agent user interface or the content user interface, distinguished where necessary.
