UI5 constants in XML views

In a JS view a password field is defined as followed:

new sap.m.InputListItem({
       label: "Password",
       content: new sap.m.Input({ value: "{app>/Password}", type: sap.m.InputType.Password })

How do I handle the same in an XML view. Sure, I can substitute the constant with a string, but this is is obviously not intention of constants.

<Input value="{app>/Password}" type="Password" />

I've tried alreay this:

type="{'sap.m.InputType.Password'}"

But it doesn't work 😔

Any ideas?
