Hi James,

On the this week's survey [1] you selected "None of the above..." and
said, "I'm not sure how to solve this but the inherent problem is that
the user may have many different ways of specifying the override. Must
all of them work - or only one? For instance in FF you can specify a
font in the options panel but equally you could also specify a font in
the user style sheet. If only one of these gives the correct results
has one met this SC? If there are multiple different ways to meet the
SC how can an author test that they all work?"

Only one override is required on for options C, D, E, and G on the survey.

The following is the test that was previously discussed and is
documented in the first comment [2] on issue 78.

## Testability

Using a bookmarklet, user stylesheet, or VIP-PDF Reader [3] change:

1.  font family to a different font family (e.g. Verdana if that is not in use)
2.  foreground color and background color to a different foreground
color and background color (e.g. white on black if that combination is
not in use)
3.  line height of all text to 1.5, letter spacing to 0.12em, and word
spacing to 0.16em.

Expected Results

*   No loss of content or functionality.


Will that work? Ideas for improvement?

For Option F on the survey we would need more rigorous testing. Wayne
has offered Validity Tests for spacing and font [4] as well as color
[5] in that vein.

Thank you.

Kindest Regards,
