Another interesting reference (Dec. 2005), with a fair amount of discussion of "picture behaviors": http://www.w3.org/TR/2005/WD-CDR-20051219/#link-activation-child-documents I notice, however, that it has all disappeared from the current CDRF editors draft (June 2006): http://www.w3.org/2004/CDF/specs/CDR/wp-1/cdf.xhtml Did it get re-factored into another document? -Lofton.
