SVGT1.2 introduces the SMIL animation element, which allows reference to a scene inside of another scene, and to control the time flow of the referred scene as can be done on a video or audio stream.
This feature requires maintaining multiple DOM trees between the referenced and the root or main SVG image. It can potentially lead to memory and performance issues with additional requirements, such as extra data validation/parsing and maintaining multiple buffers/contexts
Recommendation: Content creators should be cautious when using this feature due to the potential negative performance impact.
