DocBook 5 Document Type

A file is considered to be a DocBook 5 document when the namespace is http://docbook.org/ns/docbook.

The default schema that is used if one is not detected in the DocBook 5 file is docbookxi.rng and it is stored in [OXYGEN_INSTALL_DIR]/frameworks/docbook/5.0/rng/. Other types of schemas are also located in various folders inside the [OXYGEN_INSTALL_DIR]/frameworks/docbook/5.0/ directory (for example, XML Schema files are located in the xsd folder).

The default XML catalog, catalog.xml, is stored in [OXYGEN_INSTALL_DIR]/frameworks/docbook/5.0/.

Note: A default XML catalog and schema files for experimental DocBook 5.1 documents are also available in the [OXYGEN_INSTALL_DIR]/frameworks/docbook/5.1/ directory.
