(2) Some continually advocate a self-serving definition of "collisions" so narrow and artificial (and disparate from SSAC definitions) that it is impossible for them to occur anywhere other than newly delegated (g and cc) labels.

SAC62 defines collisions thusly:
"In the context of top level domains, the term "name collision" refers to the situation in
which a name that is properly defined in the global Domain Name System (DNS)
namespace (defined in the root zone as published by the root management partners -
ICANN, U.S. Dept. of Commerce National Telecommunication Information
Administration (NTIA), and VeriSign) may appear in a privately defined namespace (in
which it is also syntactically valid), where users, software, or other functions in that
domain may misinterpret it."

SAC66 liberalized slightly more:
"The term "name collision" refers to the situation where a name that is defined and used in
one namespace may also appear in another. Users and applications intending to use a
name in one namespace may actually use it in a different one, and unexpected behavior
may result where the intended use of the name is not the same in both namespaces."

Collisions as defined by either SSAC definition can occur in existing g and cc space.   Despite the efforts and wishes of some, collisions are a DNS problem, not a new gTLD problem.  The SSAC definitions, correctly, focus on the "misinterpretation" and "unexpected behavior" aspects - the potentially harmful aspects not arcane technicalities.

And let me add to that to please remind everyone that the definition of collision was defined specifically for the purposes of this NCAP work and received consensus in this group:

That's what Karen has been working from. It's really too late to be debating the definition of collision for the purposes of Study 1.
