 *	These abbreviations are used to keep the symbols short:
 *		Alloc	Allocation
 *		App	Application
 *		Attr	Attribute
 *		Char	Characters
 *		Desc	Descriptor
 *		Descs	Descriptors
 *		Ext	Extent
 *		Ident	Identifier
 *		Imp	Implementation
 *		Lvl	Level
 *		Max	Maximum
 *		Num	Number
 *		Ptr	Pointer
 *		Seq	Sequence
 *		Std	Standard
 *		Struct	Structure
 *		Vol	Volume
 *	The symbols are otherwise identical to the standard, and the
 *	sections of the standard to refer to are indicated.
