It doesn't matter where the inevitably incorrect and out of date list 
resides. It's a waste of time to continue discussing this editorial point.

It's incorrect for the HTML spec to call them parse errors if they can 
be interoperably parsed by HTML parsers. It's not a good use of 
Mozilla's resources to spend time debating interoperable errors.

There is probably a role for a lint tool here, but that requires 
interaction with users more than standards group involvement.

Very poor test suites are the main risk to SVG as a format, just as in 
2004[1]. Relatively speaking, the HTML serialization is a sideshow.
