@Retention(value=CLASS)
 @Target(value={METHOD,FIELD,LOCAL_VARIABLE,PARAMETER})
public @interface Subst
```
Specifies the replacement value for non-constant variables and method return values. This may help static analyzers to properly parse the concatenation of several values which is used in @Language or Pattern context.
Example:
```
 @Subst("Tahoma")
 final String font = new JLabel().getFont().getName();

 @Language("HTML")
 String message = "<html><span style='font: " + font + "; font-size:smaller'>"
   + ... + "</span></html>";
 
```
Here the parser assumes that when font appears in the concatenation its value is "Tahoma", so it can continue parsing the concatenation.
