Re: [css3-images] [css3-background] Image/media fragments and cropping

No because fragments in HTML pages have a very different meaning, they are
definitely not media fragments as defined in the MF specs, they are
identifiers found in the parsed HTML content and used through the DOM API.

The MF specs and HTML spaces are immediately incompatible without an
adaptation layer that transforms an HTML content into a media (image or
video to provide it *additional* 2D positional properties with a document
container). But both use a base <url> and generate their own set of
"fragment" identifiers.
