The <resources> element

The resources element in the configuration file defines a number of resources that can be preloaded into the configuration. It contains child elements as detailed below, in any order; most of them can appear more than once.

Element	Applies to	Values	Effect
`extensionFunction`	HE PE EE	Class that implements the ExtensionFunctionDefinition interface	Defines an "integrated extension function" written to a specific Saxon API.
`externalObjectModel`	HE PE EE	Class that implements the ExternalObjectModel interface	Defines an external object model that can be used to provide input to Saxon (and in some cases receive output): for example DOM, JDOM, XOM, etc.
`schemaComponentModel`	EE	Relative or absolute URI	A schema component model document (previously exported by Saxon) allowing fast loading of a compiled schema.
`schemaDocument`	EE	Relative or absolute URI	A schema document to be preloaded into the Saxon schema cache.

The resources element may also contain zero or more fileExtension elements as detailed below. These are used to define a mapping from file extensions to media types.

Each fileExtension element must have the following attributes, to define one pair in the mapping:

Attribute	Applies to	Values	Effect
`extension`	HE PE EE	An extension type, e.g. "xq"	A file extension.
`mediaType`	HE PE EE	A media type, e.g. "text/plain"	The media type corresponding to the file extension. The media types that are recognised by default are: application/xml, text/xml, application/html, text/html, application/atom, application/xml+xslt, and application/xml+xsd (which return an XML node); text/plain, and application/java (which return a string); application/binary (returns base64Binary); and application/json (returns the result of parsing the JSON, typically a map or array).
