Note: this collection is not a random nor representative collection of all possible SVG documents that might dynamically add content to the DOM. Rather it is a complete collection of those examples I've created over 9 years that I was able to find in a relatively brief time.

Several different bitmaps are carved by dynamically generated clipPaths, with dynamically generated animate tags.
