Chapter 8. Built-in Node Types

The JCR 2.0 specification requires that repositories have a number of node types immediately available for use by client applications. The hierarchical database defines a number of additional node types that are installed into every repository. None of these node types can be changed or modified.

8.1. Standard Node Types

The following is the CND representation of the standard JCR built-in node types: 
<jcr='http://www.jcp.org/jcr/1.0'>
<nt='http://www.jcp.org/jcr/nt/1.0'>
<mix='http://www.jcp.org/jcr/mix/1.0'>
