Hello www-svg, looking at http://dev.w3.org/SVG/profiles/1.1F2/test/svg/animate-elem-83-t.svg I started searching around for the relation of path normalisation and animation of the d attribute of path in SVG 1.1. Different from SVG tiny 1.2 the current version of SVG 1.1 (second edition) the path section has no specific text about a relation of path normalisation and animation. It is only mentioned: >>d = "path data" The definition of the outline of a shape. See Path data. Animatable: yes. 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).<< Obviously upper and lower case commands have typically (exception z/Z and an initial m/M) not the same meaning. Following the description above, one cannot have an animation starting with upper case commands in the from attribute and ending with lower case commands in the to attribute as in some subtests. And both command lists should not be different from the d attribute value itself. Therefore this is not testable in SVG 1.1 or only the correct error processing. Therefore I think, the subtests about path normalisation are applicable for SVG tiny 1.2 but not for SVG 1.1 (second edition) currently. Or did someone find another text passage about this issue? Then there is maybe some inconsistency between this and the attribute definition, that needs to be fixed/clarified. If not, either something has to be added to the section discussed above about animation about path normalisation or the test has to be changed. Olaf
