Since the implementation of xp-framework/xp-framework#328 the following features are supported (officially - they did work before but behaviour wasn't defined): new T(...), T::CONST and T::$static.

XP Language

[@action(new unittest.actions.IsPlatform("WIN"))]
[@inject(name = self::CONNECTION_DSN)]
[@values([CommandLine::$UNIX, CommandLine::$WINDOWS)]

PHP 5.3+ Syntax

#[@action(new \unittest\actions\IsPlatform("WIN"))]
