for section 8.2.7 (http://www.w3.org/TR/2009/WD-ttaf1-dfxp-20090511/#style-attribute-dynamicFlow), paragraph #5:

"If the value of this attribute is rollUp, then this value is interpreted as a shorthand value equivalent to out(line,smooth) inter(0.433s).  This time interval is defined by "Closed Caption Decoder Requirements for Analog Television," page 792 (http://edocket.access.gpo.gov/cfr_2005/octqtr/47cfr15.119.htm).

how's that?

That would be helpful. If you can suggest wording for the spec that would be even better.
