implementations

Yesterday during the meeting we found two implementations for 1.8.10
IE and QQ. Both use the same rendering/UI engine...IE. Judy wondered
if that was really 2 implementations. I queried several folks about
this issue. Ultimately, it is the working group that defines the
implementation rules, but we will have to defend them to the director.
 The consensus was that we ought to have implementations from at least
2 different rendering engines for each SC. Additionally, I checked
around with people who know engines...and mobile engines are
substantially the same as the desktop engines. I think we need to have
a discussion about this topic, and determine our rules for determining
valid implementations.
I propose that for each SC we have implementations from 2 different
rendering engines. If we find more (other engine or mobile version) so
much the better. I think this would work for SCs pertaining to
content.
I am checking on the the User Interface of the browsers. Are the user
interface of browsers with the same rendering engine different code
bases or just skins? How do we find out? If the user interface code is
unique to the browser then I think we could have 2 different
implementations from different browser with the same rendering engine.
But, only for SCs pertaining to UI components (e.g. preference
settings).

Rendering Engines
Gecko
IE - Trident
Blink
Webkit
Presto (opera) - in maintenance mode but still out there.

also, found UC Browser (400 million mobile users) java only mobile
browser on all platforms (except Apple), based on webkit but call
engine - U3.
