// Mark this tag so dependencies that use it are excluded from visibility enforcement.

//

// This does allow any prebuilt_apex to reference any module which does open up a small window for

// restricted visibility modules to be referenced from the wrong prebuilt_apex. However, doing so

// avoids opening up a much bigger window by widening the visibility of modules that need files

// provided by the prebuilt_apex to include all the possible locations they may be defined, which

// could include everything below vendor/.

//

// A prebuilt_apex that references a module via this tag will have to contain the appropriate files

// corresponding to that module, otherwise it will fail when attempting to retrieve the files from

// the .apex file. It will also have to be included in the module's apex_available property too.

// That makes it highly unlikely that a prebuilt_apex would reference a restricted module

// incorrectly.
