Document Type Association Preferences

Oxygen XML Editor uses document type associations to associate a document type with a set of functionality provided by a framework. To configure the Document Type Association options, open the Preferences dialog box and go to Document Type Association.

The following actions are available in this preferences page:

Document Type Table

This table presents the currently defined document type associations (frameworks), sorted by priority and alphabetically. Each edited document type has a set of association rules (used by the application to detect the proper document type association to use for an opened XML document). A rule is described by:

Namespace - Specifies the namespace of the root element from the association rules set (* (any) by default). If you want to apply the rule only when the root element has no namespace, leave this field empty (remove the ANY_VALUE string).
Root local name - Specifies the local name of the root element (* (any) by default).
File name - Specifies the name of the file (* (any) by default).
Public ID - Represents the Public ID of the matched document.
Java class - Presents the name of the Java class, which is used to determine if a document matches the rule.

New

Opens a Document type configuration dialog box that allows you to add a new association.

Edit

Opens a Document type configuration dialog box that allows you to edit an existing association.

Note: If you try to edit an existing association type when you do not have write permissions to its store location, a dialog box will be shown asking if you want to extend the document type.

Duplicate

Opens a Document type configuration dialog box that allows you to duplicate the configuration of an existing document type association.

Extend

Opens a Document type configuration dialog box that allows you to extend an existing document type. You can add or remove functionality starting from a base document type. All of these changes will be saved as a patch. When the base document type is modified and evolves (for example, from one application version to another) the extension will evolve along with the base document type, allowing it to use the new actions added in the base document type.

Delete

Deletes the selected document type associations.

Enable DTD/XML Schema processing in document type detection

When this option is enabled (default value), the matching process also examines the DTD/XML Schema associated with the document. For example, the fixed attributes declared in the DTD for the root element are also analyzed, if this is specified in the association rules. This is especially useful if you are writing DITA customizations. DITA topics and maps are also matched by looking for the DITAArchVersion attribute of the root element. This attribute is specified as default in the DTD and it is detected in the root element, helping Oxygen XML Editor to correctly match the DITA customization.

Only for local DTDs/XML Schemas

When this option is enabled (default value), only the local DTDs / XML Schemas will be processed.

Enable DTD/XML Schema caching

When this option is enabled (default value), the associated DTDs or XML Schema are cached when parsed for the first time, improving performance when opening new documents with similar schema associations.
