/*! \page enumeration enumeration
XML schema also allows a simple type restriction to be defined by enumeration.
OWL Enumerations allow classes to be defined extensionally, in terms of their membership.
For data-types, the class of values is specified as an OWL DataRange, with OWL oneOf listing the permitted range of values.
\include enumeration.xsd
Because xs:QNames are not recommended for use in RDF (they depend on locally defined prefixes)
they are fully expanded to form absolute URIs. The QNames that appear in the schema are unprefixed
and so are defined in the default XML namespace.
