            Bug ID: 202411
           Summary: Make the SVG properties of SVGViewSpec modifiable but
                    detached properties
           Product: WebKit
           Version: WebKit Nightly Build
          Hardware: Unspecified
                OS: Unspecified
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: SVG
          Assignee: webkit-unassigned at lists.webkit.org

The SVG1.1 specs did not mention that the proprieties of SVGViewSpec are read-only. See https://www.w3.org/TR/SVG11/types.html#InterfaceSVGViewSpec. The expected implementation is to throw an exception if JavaScript tries to modify any of them. I think they were implemented this way because there is an SVGElement which owns the attributes of the SVGViewSpec since SVGViewSpec is not derived from SVGElement.

But this complicates the logic for accessing all the SVGProperties. So I think the right way to deal with these properties is to make them modifiable but detached properties.
