list of prefix definitions contains a list of definitions of prefixing schemes used in data.pointer values, showing how abbreviated URIs using each scheme may be expanded into full URIs.

In this example, two private URI scheme prefixes are defined and patterns are provided for dereferencing them. Each prefix is also supplied with a human-readable explanation in a p element.

Private URIs using the psn prefix are pointers to person elements in the personography.xml file. For example, psn:MDH dereferences to personography.xml#MDH.

Private URIs using the bibl prefix can be expanded to form URIs which retrieve the relevant bibliographical reference from www.example.com.
