All Implemented Interfaces:

```
public class ThemeTag
extends MessageTag
```
Custom tag to look up a theme message in the scope of this page. Messages are looked up using the ApplicationContext's ThemeSource, and thus should support internationalization.
Regards a HTML escaping setting, either on this tag instance, the page level, or the web.xml level.
If "code" isn't set or cannot be resolved, "text" will be used as default message.
Message arguments can be specified via the arguments attribute or by using nested <spring:argument> tags.
