Field Decorators and Validation

This document describes Use Cases and Solutions for field decorators of (1) Content Assist, (2) Required Fields, and (3) Errors/Warnings. Each of these indicators are shown in various UI contexts, such as Dialog Boxes, Wizards, and Forms, in order to describe the design issues and apply a consistent solution where possible. The main techniques that are described in the Blueprint Specifications and Solutions refer to icon/text treatment (size and position) at the Control-level, as well as messages at the UI-level.
