For add-ons that have this option (see Supporting Add-ons table shown on the right), administrators can establish some spaces as being secure places for restricted macro capabilities. This allows administrators to use space permissions, rather than "edit" page restrictions, to control who can create or edit content that uses a restricted macro.
An administrator has a space that already has space-level permissions governing who can create content in the space, limiting it to certain trusted users. The administrator would like to allow restricted macros to be used on pages in that space without needing to use "edit" page restrictions.
The following syntax in the Macro Security add-on's configuration properties file will allow content within a space to be authorized without requiring a page restriction: space:SPACEKEY
This syntax can be used instead of or in addition to specifying trusted users and/or groups in the list of authorized entries. In addition, it can be used on Use Restrictions as well as the Parameter Restrictions in the configuration properties file. (Refer to the Understanding How Macro Security Works page for more information about Use Restrictions and Parameter Restrictions.)
