Here are the places we use the term (the first one is actually not a use of real-time events) 1.2.3 Real-time captions <http://www.w3.org/WAI/GL/WCAG20/appendixA.html#captionsdef> are provided for live multimedia <http://www.w3.org/WAI/GL/WCAG20/appendixA.html#multimediadef> .

[How to meet 2.2.4 <http://www.w3.org/WAI/GL/WCAG20/WD-UNDERSTANDING-WCAG20-20060117/Overvi ew.html#time-limits-no-exceptions> ] The new definition is real-time events events that are live Interesting. Should we just plug in "live events"? (or would we need to define that) Gregg ------------------------ Gregg C Vanderheiden Ph.D. Professor - Depts of Ind. Engr. & BioMed Engr.
