The following tests are failing on IE10 on the build server:
The Renderer-related tests seem to failing due to IE recognizing "id" and "rsf:id" as the same attribute. I get messages about the DOCTYPE being invalid as well, perhaps these are related?
These seem to be legitimate test failures, and I think are similar to failures on IE8 as well. It looks to me like these failures relate to focus management, but I'm not certain.
