IFRAME tag defined in the document does not have a valid TITLE attribute.

A TITLE attribute of a IFRAME tag is valid if the following conditions apply: it exists; it is not an empty string (""), and it is not a blank string(" ").

Define a valid TITLE attribute for the IFRAME tag.

Title the frame to help frame identification and navigation by describing concisely the frame's content and role in the page.

Since the TITLE attribute is not widely supported, providing titles as normal text at the top of the contents of each frame is sufficient for the purposes of 508 rule 1194.22(i).

A TITLE string value is valid if it meets the following requirements:

• It does not contains any HTML tags
• It is not an empty string ("")
• It is not a blank string (" ")

Frames are good for implementing complex navigational structures. However, in many cases this added complexity may become an obstacle for many users. Make sure your framed page can be accessed by any user using any possible technology in any possible context.

A general user interface design guideline is "to provide context and orientation information to help users understand complex pages or elements."

Providing contextual information about the relationships between elements can be useful for all users. Complex relationships between parts of a page may be difficult for people with cognitive or visual disabilities to interpret.

Cognitive disabilities does not refer only to people whom are mentally challenged, but also people who work under specific adverse contexts, such as people using an e-ticketing service in an airport hall, a speaking browser by phone in a noisy environment, a PDA where a quick decision is required, or a browser during a meeting where changing the mental focus is difficult.

Similarly, visually disabled people also include people who forget their glasses at home, who use a poorly lit display in a dark environment, or who use a speaking browser or screen reader over a phone.
