Datatype datatype is identified by IRI

Its lexical space is the concatenation of the lexical form of an
xsd:decimal, an optional space, and a unit that can be either a metric length unit, or an imperial length unit, in abbreviated form or as full words, in singular or plural form. The value space correspond to the set of lengths, as defined by the International Systems of Quantities, i.e., any quantity with dimension distance. The lexical-to-value mapping maps lexical forms with units in the metric system to their corresponding length according to the International Systems of Quantities, while the forms with an imperial unit are mapped to their equivalent length according to the International yard and pound agreement.
For example, all literals below are well formed and share the same value.
