Are dynamic hostnames based on a pattern supported?

Is there support for a case like this :

`@DeepLink("http://{name}.example.com/deepLink")`

Looking for variable host names here.

Review the deep-link annotation and annotation-processor implementation to determine how host patterns are currently parsed and matched. Define whether variable hostnames such as `{name}.example.com` should be supported, then document the required behavior and verify it with focused tests in the relevant implementation area.
