THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!
Legend for Javascript column color usage:
Black: JavaScript matches ActionScript
Red: solution not agreed upon
Blue: solution looks good, need consencus to approve (use Comments or Notes column)
Green: solution agreed upon

To "strongly" type JS, we use the Google Closure annotations. These are JSDoc block that go with function or variable declarations and give the Closure Compiler hints as to the type of variables, arguments and return values. |

Attribute Keywords |

All JS 'classes' are dynamic by nature, so there's no need for this keyword? |

no annotation needed |
Is this a runtime attribute, or is it handled at compile time? If the latter, we can just leave it out as attempts to subclass this type are handled (blocked) on the AS side anyway? |
