Each standard module determines its subspace in the Bitrix name space which coincides with the module name. For example, for the forum module Bitrix\Forum will be the name space, and for the main module – Bitrix\Main.

To abridge it, declare a synonym at the start of the file and use an abridged variant of the call afterwards:
