Dear Scalable Vector Graphics Working Group, http://www.w3.org/TR/2005/WD-SVGMobile12-20050413/paths.html section 8.1 notes [...] Path data animation is only possible when each path data specification within an animation specification has exactly the same list of path data commands as the d attribute. If an animation is specified and the list of path data commands is not the same, then the animation specification is in error (see Error Processing). The animation engine interpolates each parameter to each path data command separately based on the attributes to the given animation element. Flags and booleans are interpolated as fractions between zero and one, with any non-zero value considered to be a value of one/true. [...] It is not clear whether this is meant to prohibe discrete animation of different paths (e.g., set M...L... to M...C...), please change the draft such that this is clear; note that existing implementations fail to implement this restriction. It is not clear what it means for two instances of path data to have the same list of path data commands, may there be differnces with respect to absolete versus relative commands, implied commands, command parameters, etc. please change the draft such that equivalence is well-defined. It is not clear what the note about "flags" and "booleans" is trying to cover, SVG Tiny 1.2 does not allow elliptical arcs where flags would be relevant, and booleans do not seem to exist in path data. Please remove this note or change the draft such that it is obvious why it is needed. regards, -- Björn Höhrmann · mailto:bjoern@hoehrmann.de · http://bjoern.hoehrmann.de Weinh.
