0. BL
Definition	The Boolean type stands for the values of two-valued logic. A Boolean value can be either true or false, or, as any other value may be NULL.
Control	1..*
Logical Container	ADHA ClinicalDocument (CDA Class)
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Invariants	value-null: value and nullFlavor are mutually exclusive (one must be present) (`(value \| nullFlavor).count() = 1`)
2. BL.value
Definition	The Boolean type stands for the values of two-valued logic. A Boolean value can be either true or false, or, as any other value may be NULL.
Control	0..1
Type	boolean(bl: Boolean)
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
XML Format	In the XML format, this property is represented as an attribute.

0. BL
Definition	The Boolean type stands for the values of two-valued logic. A Boolean value can be either true or false, or, as any other value may be NULL. Base definition for all types defined in FHIR type system.
Short	Base for all types and resources
Control	10..*
Is Modifier	false
Logical Container	ADHA ClinicalDocument (CDA Class)
XML Format	In the XML format, this property has the namespace `urn:hl7-org:v3`.
Invariants	value-null: value and nullFlavor are mutually exclusive (one must be present) (`(value \| nullFlavor).count() = 1`)
2. BL.nullFlavor
Definition	If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
Control	0..1
Binding	The codes SHALL be taken from CDANullFlavor (required to `http://hl7.org/cda/stds/core/ValueSet/CDANullFlavor`)
Type	code(cs: Coded Simple Value)
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
XML Format	In the XML format, this property is represented as an attribute.
Label	Exceptional Value Detail
4. BL.value
Definition	The Boolean type stands for the values of two-valued logic. A Boolean value can be either true or false, or, as any other value may be NULL.
Control	0..1
Type	boolean(bl: Boolean)
Primitive Value	This primitive element may be present, or absent, or replaced by an extension
XML Format	In the XML format, this property is represented as an attribute.
