Ontological definition of the reference provided in href

href

A link to some reference

type

optional xsi:type. If not given, will use either "LiteralMeta" or "ResourceMeta" as determined by the presence of either a property or a href value.

children

Optional element containing any valid XML block (XMLInternalElementNode class, see the XML package for details).

Details

User must either provide property+content or rel+href. Mixing these will result in potential garbage. The datatype attribute will be detected automatically from the class of the content argument.
