Nobody has or will ever implement them; the SVG Tiny 1.2 rules should be 
considered the way that SVG 1.0 and 1.1 define error handling.

In that case, I would raise this as an issue with the working group -- UA 
processing shouldn't be left undefined in such cases (especially since 
such cases are likely to be common on the Web -- sites and network 
connections go down all the time).
