After further discussions, I'm not sure my original position is tenable 
without causing undue inconvenience in writing testcases. Nevertheless 
where optional features exist we need some critera to determine whether we 
should include them in the official testsuite. A reasonable policy might 
be "features that all four major engines are committed to implementing are 
OK to test without a precondition check". It seems that SVG-in-img (and 
hence SVG-in-drawImage) meet this criterion (whereas, say, PDF-in-<img> 
would not). Therefore I no longer have a principled objection to the 
substance of this testcase.
