>+        Parsing the SVG lists is just ad-hoc. There is no single rule for:
>+
>+        -- The leading spaces: SVGLengthList SVGNumberList treated them as an error
>+           while SVGTransformList and SVGPointList were just skipping them.
>+        -- Status of the list in case of an error: SVGTransformList was clearing
>+           the list if an error was detected. The other lists were leaving whatever
>+           is parsed before the error happened but return an error.
>+        -- Reporting an error message in the console: SVGPointList was reporting
>+           an error message if a parsing error happened. The other type of lists
>+           were just silent when an error happens.
>+        -- Delimiters: SVGNumberList assume the white spaces are the only allowed
>+           delimiter. All other lists allow the comma also as a delimiter.
>+        -- Extra text at the end: SVGTransformList was not reporting an error if
>+           there is extra text at the end. Other list were returning false.
>+
>+        In addition to that, the parsing code was repeated in every SVGList
>+        super class. Instead parsing the list should be in SVGValuePropertyList
>+        and SVGPrimitiveList. And parsing the item should be moved to the value
>+        property class or the SVGPropertyTraits of the primitive.
>+
>+        SVGViewSpec parsing is cleaned up in the patch as well. Parsing of this
>+        class is needed to create the view for a fragment.
