The test verifies that when you call insertNode() on a range, the node 
that is passed is inserted into the range, as is required by DOM2 range 
section 2.9. Inserting Content, sentences 1 and 2 (before and after the 
code snippet).

These sentences are contradicted by the more generic sentences in section 
2.12.1. Insertions, which don't take insertNode() into account for the 
case of a collapsed range, and thus end up not implementing the 
requirement in the former section.

I hold that the intent of the spec is clear, in that it would be pretty 
dumb for an API for inserting nodes into a range didn't actually insert 
nodes into a range; however, I agree that it is possible to interpret the 
spec in a way that assums that the generic rules in the latter section 
override the statements in the former section, hence my proposal that we 
raise this as an errata.

Right, that's why I raised on the list, so that we can discuss it.
