Kiran, What you are really talking about is how a system closed to screen reading AT, but which provides its own self-voicing functionality, deals with certain media. And how agencies deal with this situation. Clearly we need to capture somewhere that a federal agency shall not procure (or produce and provide to the public) eBooks with a "do not speak flag" set on them. That is the fundamental issue. Since with eBooks we are talking about non-embedded content, we need to capture this as an issue/property of non-embedded content. While you could fix this in some sense in the eBook (e.g. "don't purchase eBooks which respect a "do not speak" flag), such a remedy would be inappropriately broad. I wonder if this is simply an example of a necessary provision that doesn't come directly out of WCAG A/AA (since you don't have DRM-encoded HTML!). So perhaps this needs a remedy tailored to DRM situations - a provision noting that no content shall be acquired / disseminated / used where such content expressly disables accessibility features (such as the "no not speak" flag of xyz format eBooks).
