(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.
