Current behavior
The documentation for the ViewChild, and ContentChild decorators does not make clear what qualifies as a valid selector for specifying a target element or directive. Even if one can infer from the various code examples that Component classes, Directive classes, and standard CSS selectors are valid options I see no documentation that indicates template reference variables may be used as selectors. This has apparently already confused at least one other person.
