chapter 7.6 of the spec 'The transform attribute' reads: "The value of the transform attribute is a <transform-list>, which is defined as a list of transform definitions, which are applied in the order provided. The individual transform definitions are separated by whitespace and/or a comma." consider an element applied to which is a list of elementary transforms Ai <elem transform="An .. A2 A1" /> we can yield the same result via <elem transform="matrix(An*...*A2*A1)" /> by multiplying the transformation matrices of the elementary transforms in exactly that order. Applying those transforms to a point we can calculate the result matrix first and then transform the point, as in .. (An*...*A2*A1) * p or apply every single transformation matrix consecutively to the point, as in .. (An*(...*(A2*(A1 * p)))..) With this the above formulation "in the order provided" is misleading or even wrong. It should read "from right to left". -- stefan goessner
