The <xquery> element

The xquery element of the configuration file contains properties specific to XQuery. Remember that these are defaults, they can always be overridden for specific queries. An attribute whose value is set to a zero-length string is ignored, the effect is the same as omitting the attribute.

Attribute	Applies to	Values	Effect
`allowUpdate`	EE	true\|false	Indicates whether XQuery Update syntax is accepted.
`constructionMode`	HE PE EE	preserve\|strip	Default value for construction mode in the static context.
`defaultElementNamespace`	HE PE EE	Namespace URI	Default namespace for elements and types.
`defaultFunctionNamespace`	HE PE EE	Namespace URI	Default namespace for functions.
`emptyLeast`	HE PE EE	true\|false	True if the empty sequence comes first in sort order.
`inheritNamespaces`	HE PE EE	true\|false	Default value for "inherit namespaces" in the static context.
`moduleUriResolver`	HE PE EE	Name of a class implementing ModuleURIResolver	Used for locating query modules referenced by "import module".
`multipleModuleImports`	EE	true\|false	If set to true, the XQuery processor attempts to fetch an XQuery module appearing in an `import module` directive, whether or not a module with that module URI has already been loaded, unless the location URI of the existing module is the same as that of the requested module.
`preserveBoundarySpace`	HE PE EE	true\|false	Policy for preserving boundary space within direct element content.
`preserveNamespaces`	HE PE EE	true\|false	Default value for "preserve namespaces" in the static context.
`requiredContextItemType`	HE PE EE	An item type, e.g. `document-node()`	The required type for the context item.
`schemaAware`	EE	true\|false	True if the query makes use of schema information.
`staticErrorListener`	HE PE EE	Name of a class implementing the JAXP interface `javax.xml.transform.ErrorListener`	Receives notification of static errors occurring in a Query.
`version`	HE PE EE	1.0\|3.0\|3.1	Indicates whether XQuery 3.0 or 3.1 syntax is accepted. From Saxon 9.8, an XQuery 3.1 processor is always used by default. So setting this property has no effect.
