Test xf:switch

First case is selected by default

I am case 1, in switch 1 I am case 2, in switch 1 I am case 3, in switch 1

Switch 1, case 1 Switch 1, case 2 Switch 1, case 3

Second case has `@selected="true"`

I am case 1, in switch 2 I am case 2, in switch 2 I am case 3, in switch 2

Switch 2, case 1 Switch 2, case 2 Switch 2, case 3

Second and third cases have `@selected="true"`, but the second case should be the default

I am case 1, in switch 3 I am case 2, in switch 3 I am case 3, in switch 3

Switch 3, case 1 Switch 3, case 2 Switch 3, case 3
