/* This header file does not include internal Node definition,
   i.e. AML_ROOT_NODE, AML_OBJECT_NODE, etc. The node definitions
   must be included by the caller file. The function prototypes must
   only expose AML_NODE_HANDLE, AML_ROOT_NODE_HANDLE, etc. node
   definitions.
   This allows to keep the functions defined here both internal and
   potentially external. If necessary, any function of this file can
   be exposed externally.
   The Api folder is internal to the AmlLib, but should only use these
   functions. They provide a "safe" way to interact with the AmlLib.
