sed s/computed/used/g (based on our last email regarding the "computed value" field) Is that correct?

The actual values in user agents may therefore be clamped to implementation-dependent minimum and maximum boundaries. For example: although the 0Hz frequency can be legitimately computed, it may be clamped to a more meaningful value in the context of the speech synthesizer. > " > > and for computed values: > > " > Computed absolute frequency values that are negative are clamped to zero Hertz. > " > > Author-provided values are handled slightly differently: > > " > When a negative value is provided, it is clamped to zero. > " > > http://dev.w3.org/csswg/css3-speech/#voice-pitch
