Specification

Summary
This feature enables the application of transformation properties-such as 
scaling, rotation, translation, and skewing-directly to the <svg> root element 
via its transform attribute. This enhancement allows developers to manipulate 
the entire SVG coordinate system or its contents as a whole, providing greater 
flexibility in creating dynamic, responsive, and interactive vector graphics. 
By supporting this attribute, the SVG element can be transformed without 
requiring additional wrapper elements or complex CSS workarounds, streamlining 
the process of building scalable and animated web graphics.
