  end;

	Name	Description
	AsString	Returns a string representation of the fact slot
	DefaultDynamic	Specifies if the SlotDefault value is dynamic. If the SlotDefault value is dynamic, every time a fact is generated with this fact slot, the SlotDefault value must be resolved first - this allows the default value of a fact slot to come from the evaluation of a function call or variable. Otherwise, if the DefaultDynamic property is False, the SlotDefault property is added unchanged into the fact's slot
	ExtendedTypeInfo	Defines the extended type information for the fact slot
	Fuzzy	Returns whether this fact slot is a fuzzy fact slot, with acts as a fuzzy variable
	Name	Defines the name of the slot
	SlotDefault	Defines the default value this slot should take when a new fact is created
	SlotType	Identifies the allowable data types (a set of TIEType type) that this slot can hold

	Name	Description
	CreateValidDefault(Boolean)	Creates a valid default value based on the defined type. If the AsList parameter is TRUE, this method returns a list value (AsList) containing correct values. This method ensures the created value will pass all the constraints and limits of the type definition
	GetDefaultDynamic	Accessor method for the DefaultDynamic property
	GetExtendedTypeInfo	Accessor method for the ExtendedTypeInfo property
	GetInvalidValueString(IIEValue)	Returns a string describing why the Value parameter is NOT a valid value for this defined type. If the Value is valid for the type, this method returns an empty string
	GetName	Accessor method for the Name property
	GetSlotDefault	Accessor method for the SlotDefault property
	GetSlotType	Accessor method for the SlotType property
	GetTemplateName	Returns the name of the fact template that owns this slot
	get_AsString	Represents method get_AsString.
	get_DefaultDynamic	Represents method get_DefaultDynamic.
	get_ExtendedTypeInfo	Represents method get_ExtendedTypeInfo.
	get_Fuzzy	Represents method get_Fuzzy.
	get_Name	Represents method get_Name.
	get_SlotDefault	Represents method get_SlotDefault.
	get_SlotType	Represents method get_SlotType.
	IsFuzzy	Accessor method for the Fuzzy property
	IsValid(IIEValue)	Returns TRUE if the specified Value is a valid value for the fact slot based on the type information
	SetDefaultDynamic(Boolean)	Accessor method for the DefaultDynamic property
	SetExtendedTypeInfo(IIEDefinedType)	Accessor method for the ExtendedTypeInfo property
	SetName(TIEName)	Accessor method for the Name property
	SetSlotDefault(IIEValue)	Accessor method for the SlotDefault property
	SetSlotType(TIETypes)	Accessor method for the SlotType property
	set_DefaultDynamic(Boolean)	Represents method set_DefaultDynamic(Boolean).
	set_ExtendedTypeInfo(IIEDefinedType)	Represents method set_ExtendedTypeInfo(IIEDefinedType).
	set_Name(TIEName)	Represents method set_Name(TIEName).
	set_SlotDefault(IIEValue)	Represents method set_SlotDefault(IIEValue).
	set_SlotType(TIETypes)	Represents method set_SlotType(TIETypes).
	ToString	Returns a string representation of the fact slot

Every fact in the inference engine is made up of slots, similar to the properties of an object. A person fact may have slots for hair color, eye color, height, weight, or whatever else the designer of the expert system may think of.

The TFactSlot class implements this interface for the IECS
