NameFlagsCard.TypeDescription & Constraintsdoco
.. ElementDefinition C 0..* ElementDefinition Definition of an element in a resource or extension
eld-2: Min <= Max
eld-5: if the element definition has a contentReference, it cannot have type, defaultValue, fixed, pattern, example, minValue, maxValue, maxLength, or binding
eld-6: Fixed value may only be specified if there is one type
eld-7: Pattern may only be specified if there is one type
eld-8: Pattern and fixed are mutually exclusive
eld-11: Binding can only be present for coded elements, string, and uri if using FHIR-defined types
eld-13: Types must be unique by code
eld-14: Constraints must be unique by key
eld-15: default value and meaningWhenMissing are mutually exclusive
eld-16: sliceName must be composed of proper tokens separated by "/"
eld-18: Must have a modifier reason if isModifier = true
eld-19: Element path SHALL be expressed as a set of '.'-separated components with each component restricted to a maximum of 64 characters and with some limits on the allowed choice of characters
eld-20: The first component of the path should be UpperCamelCase. Additional components (following a '.') should be lowerCamelCase. If this syntax is not adhered to, code generation tools may be broken. Logical models may be less concerned about this implication.
eld-22: sliceIsConstraining can only appear if slicename is present
eld-24: pattern[x] should be used rather than fixed[x]
eld-25: Order has no meaning (and cannot be asserted to have meaning), so enforcing rules on order is improper
eld-27: Mappings SHOULD be unique by key
eld-28: Can't have valueAlternatives if mustHaveValue is true
... id 0..1 id Unique id for inter-element referencing
... Slices for extension 0..* Extension Additional content defined by implementations

Binding: UCUM Codes (required)

.. ElementDefinition C 0..* ElementDefinition Definition of an element in a resource or extension
eld-2: Min <= Max
eld-5: if the element definition has a contentReference, it cannot have type, defaultValue, fixed, pattern, example, minValue, maxValue, maxLength, or binding
eld-6: Fixed value may only be specified if there is one type
eld-7: Pattern may only be specified if there is one type
eld-8: Pattern and fixed are mutually exclusive
eld-11: Binding can only be present for coded elements, string, and uri if using FHIR-defined types
eld-13: Types must be unique by code
eld-14: Constraints must be unique by key
eld-15: default value and meaningWhenMissing are mutually exclusive
eld-16: sliceName must be composed of proper tokens separated by "/"
eld-18: Must have a modifier reason if isModifier = true
eld-19: Element path SHALL be expressed as a set of '.'-separated components with each component restricted to a maximum of 64 characters and with some limits on the allowed choice of characters
eld-20: The first component of the path should be UpperCamelCase. Additional components (following a '.') should be lowerCamelCase. If this syntax is not adhered to, code generation tools may be broken. Logical models may be less concerned about this implication.
eld-22: sliceIsConstraining can only appear if slicename is present
eld-24: pattern[x] should be used rather than fixed[x]
eld-25: Order has no meaning (and cannot be asserted to have meaning), so enforcing rules on order is improper
eld-27: Mappings SHOULD be unique by key
eld-28: Can't have valueAlternatives if mustHaveValue is true
