Hi Rick, Thank you very much for your mail. (2014/04/18 3:08), Rick Waldron wrote: > ... > Agreed, and a step further would be to specify that only valid > properties are recognized. Here's a naive hack to illustrate: I might have misunderstood this point. The algorithm in 5.15.2[1] begins by creating a list of supported property names and only calling [[Get]] on properties in the input object whose property name is in the list of supported property names. It still iterates over the list of properties in the input object (not the list of supported property names) for performance reasons: in the common case, the input object only has one or two properties whilst the list of supported property names is long and is expected to grow over time. Does that match what you had in mind? Thanks again, Brian [1] http://dev.w3.org/fxtf/web-animations/#processing-a-keyframe-object (Unfortunately, named anchors don't currently work very well but it's section 5.15.2, Processing a Keyframe object)
