In the case of passthrough, where its intent is to "pass through" to a particular target runtime, the runtime argument seems most appropriate to me. I suppose we should add some sanity checking that the runtime argument is a valid runtime.
If you really need a passthrough conditional to other properties, you can do so in a <script> tag. --- The problem we are trying to solve here is that <switch> cannot be used in a binary library (because its semantics are that it is evaluated at parse time). Another approach would be to change switch to have an 'evaluation time' property, but that seemed like generality we didn't need.
