To configure global options for XQuery transformation and validation scenarios that use the Saxon HE/PE/EE engine, open the Preferences dialog box (Options > Preferences) and go to XML > XSLT-XQuery > XQuery > Saxon-HE/PE/EE.

Oxygen XML Editor allows you to configure the following XQuery options for the Saxon 9.9.1.5 Home Edition (HE), Professional Edition (PE), and Enterprise Edition (EE):
Use a configuration file ("-config")
Sets a Saxon 9.9.1.5 configuration file that is used for XQuery transformation and validation scenarios.
Enable Optimizations ("-opt")
This option is selected by default, which means that optimization is enabled. If not selected, the optimization is suppressed, which is helpful when reducing the compiling time is important, optimization conflicts with debugging, or optimization causes extension functions with side-effects to behave unpredictably.
Use linked tree model ("-tree:linked")
This option activates the linked tree model.
Recoverable errors ("-warnings")
Specifies how dynamic errors are handled. The following options can be selected:
  • Recover silently ("silent") - Continues processing without reporting the error.
  • Recover with warnings ("recover") - Issues a warning but continues processing.
  • Signal the error and do not attempt recovery ("fatal") - Issues an error and stops processing.
Strip whitespaces ("-strip")
Specifies how the strip whitespaces operation is handled. You can choose one of the following values:
  • All ("all") - Strips all whitespace text nodes from source documents before any further processing, regardless of any @xml:space attributes in the source document.
  • Ignore ("ignorable") - Strips all ignorable whitespace text nodes from source documents before any further processing, regardless of any @xml:space attributes in the source document. Whitespace text nodes are ignorable if they appear in elements defined in the DTD or schema as having element-only content.
  • None ("none") - Strips no whitespace before further processing.
The following option is available for Saxon 9.9.1.5 Professional Edition (PE) and Enterprise Edition (EE) only:
Allow calls on extension functions ("-ext")
If selected, calls on external functions are allowed. Selecting this option is recommended in an environment where untrusted stylesheets may be executed. It also disables user-defined extension elements and the writing of multiple output files, both of which carry similar security risks.
The options available specifically for Saxon 9.9.1.5 Enterprise Edition (EE) are as follows:
Validation of the source file ("-val")
Requests schema-based validation of the source file and of any files read using document() or similar functions. It can have the following values:
  • Schema validation ("strict") - This mode requires an XML Schema and allows for parsing the source documents with strict schema-validation enabled.
  • Lax schema validation ("lax") - If an XML Schema is provided, this mode allows for parsing the source documents with schema-validation enabled but the validation will not fail if, for example, element declarations are not found.
  • Disable schema validation - This specifies that the source documents should be parsed with schema-validation disabled.
Validation errors in the result tree treated as warnings ("-outval")

Normally, if validation of result documents is requested, a validation error is fatal. Selecting this option causes such validation failures to be treated as warnings.

Write comments for non-fatal validation errors of the result document
The validation messages for non-fatal errors are written (wherever possible) as a comment in the result document itself.
Enable XQuery update ("-update:(on|off)")

This option controls whether or not XQuery update syntax is accepted. The default value is off.

Backup files updated by XQuery ("-backup:(on|off)")
If selected, backup versions for any XML files updated with an XQuery Update are generated. This option is available when the Enable XQuery update option is selected.
