Conditional css class property

I have seen a lot of class bindings adding css class if condition is true, like: {value: IsActive ? "active" : ""}. I think we could implement some nicer way to code this behavior, something similar to knockout css binding.

Maybe it could be attribute group, like RouteLink Param-…

<div CssClass-active="{value: IsActive}">
    ...

Implemented

Example:

<div Class-italic="{value: Italic}" Class-blue="{value: Blue}" Class-bordered="{value: Bordered}">
        DotVVM is awesome!
</div>
