Some proposed changes to wording for clarification of flow buffer semantics:

B.2 compute the difference between the content produced:

“in the procedure described above, the content of a flow buffer at time Tk is considered to be significantly different from the content of the same flow buffer at time Tk+1 if the set of glyph areas that would be produced by performing synchronic flow processing on intermediate  synchronic document at time Tk differs from the set of glyph areas that would be produced by performing synchronic flow processing on intermediate  synchronic document at time Tk+1 in any of the following ways:”

“then instantaneously replace” -> “replace at time T(k+1)”

B.3.1
“if the value of the fill interval is auto, then the computed fill interval from time T(k) up to but not including T(k+1) is equal to the difference between the time coordinate associated with the most temporally prior beginning point of an active duration of some content unit present in the flow buffer at time T(k+1) and the most temporally subsequent ending point of an active duration of some content unit present in the flow buffer at time T(k+1) divided by the number of fill units currently available in the flow buffer at time T(k+1).”

B.3.1 and B.3.2 (assuming clear interval is retained)
“if the value of the clear interval is auto, then the computed clear interval from time T(k) up to but not including T(k+1) is equal to the difference between the time coordinate associated with the most temporally prior beginning point of an active duration of some content unit present in the presentation region at time T(k)and the most temporally subsequent ending point of an active duration of some content unit present in the presentation region at time T(k) divided by the number of clear units currently available in the presentation region at time T(k).”
