; THIS IS A WORKAROUND for the current limitations of the module policy language
; This should be used sparingly until we figure out a saner way to achieve the
; stuff below, for example, by improving typeattribute statement of module
; language.

; Apps, except isolated apps, are clients of Allocator HAL
; Unfortunately, we can't currently express this in module policy language:

; Unfortunately, we can't currently express this in module policy language:
