An implementation of the XML Schema (XSD) datatype system for use within `RDF.Literal.Datatype` system.
|
|

It consists of
|
|
|
|
- `RDF.XSD.Datatype`: a more specialized `RDF.Literal.Datatype` behaviour for XSD datatypes
|
|
- `RDF.XSD.Datatype.Primitive`: macros for the definition of `RDF.Literal.Datatype` and
|
|
`RDF.XSD.Datatype` implementations for primitive XSD datatypes
|
|
- `RDF.XSD.Datatype.Restriction`: macros for the definition of `RDF.Literal.Datatype` and
|
|
`RDF.XSD.Datatype` implementations for derived XSD datatypes
|
|
- `RDF.XSD.Facet`: a behaviour for XSD facets which can be used to constrain values on
|
|
datatype derivations
