Section 508 Part 1194.22 Subpart i states: Frames shall be titled with text that facilitates frame identification and navigation.
Name each frame so people know what the purpose is and whether it contains navigation links or content.
Each frame needs to have a meaningful title that clearly describes the frame's purpose as navigation or content. Frames should be labeled in three different places to ensure accessibility (Title tag at the start of HTML, and inside the frame tag itself using Title and Name). There should be a link to a no frames version of the website if a user cannot access frames or the browser does not support frames.
