Summary of Issue: Why do contrast requirements not apply to lines in diagrams and such?
Comment (Including rationale for any proposed change):
Why do contrast requirements only apply to text and images of text? What about other important parts of informative images - such as lines in diagrams, icons or symbols in maps etc.? Or what about other non-text-elements such as the borders of input fields?

Users can define their own colours for text in all modern user agents, however they cannot control the color in images. Therefore sufficiant contrast is even more important for images than for text.

Proposed Change:
All essential parts of a web page need to have sufficient contrast - not only text and images of text.
