Similar to UIHint to select which view to use for Properties and Blocks, I should be able to select different PropertyModels to be used for ContentAPI.

An example decorating my property similar to:

[JsHint("MyString")]
public virtual string MyProperty { get; set; }

Then I should be able to point out which PropertyModel to use to render my string property in a specific way for the JsHint "MyString".

Note that the attribute "JsHint" is just an example, any other suggestion would be fine with my as long as it's possible to pinpoint different ModelTypes.
