I'd like to wait to see what the results of the WebKit experiments are, 
and whether that indicates whether the non-HTMLAllCollection callers 
will be removed from the HTML spec.

For the moment, I will give Anne's suggestion a try -- I'll leave it in 
the spec, and rename it to legacycaller.;r2=1.395;f=h

Jonas, can you indicate whether this resolution is satisfactory?
