ERROR: SysML-1.6: Figure D.2: the original spec figure appears to show Real owned by the ModelLibrary 'Automotive Value Types' without an explicit element import.
Webel Best Practice: Webel: SysMLv1.x: AVOID (where possible) SysML Unit names that are the same as unit symbols. Unit names SHOULD start with a lower case Latin alpha letter. Custom Unit names should be a single lower case word or lowerCamelCase.

[CONVENTION, NAMING, POLICY]{STRONG} Webel: SysMLv1.x: AVOID (where possible) SysML Unit names that are the same as unit symbols. Unit names SHOULD start with a lower case Latin alpha letter. Custom Unit names should be a single lower case word or lowerCamelCase.
Snippets (quotes/extracts)
  [SysML-1.6] SysML ValueType adds an ability to carry a unit of measure and quantity kind associated with the value.
  [SysML-1.6] A quantity kind is a kind of quantity that may be stated in terms of defined units, but does not restrict the selection of a unit to state the value. A unit is a particular value in terms of which a quantity of the same quantity kind may be expressed.
  [SysML-1.6] unit : InstanceSpecification [0..1] A unit, represented by an InstanceSpecification classified by a kind of SysML Unit, in terms of which the magnitudes of other quantities that have the same quantity kind can be stated.
  [SysML-1.6] quantityKind : InstanceSpecification [0..1] A kind of quantity, represented by an InstanceSpecification classified by a kind of SysML QuantityKind, that may be stated by means of units. A value type may optionally specify a quantity kind without any unit.
