The <serialization> element

The serialization input element of the configuration file contains default serialization properties. These are used as defaults for serialization properties that are not present in an xsl:output declaration in an XSLT stylesheet. They currently have no effect on serialization of secondary result documents, or on serialization of XQuery results. The values are used only at stylesheet compile time. When a stylesheet is loaded from a Stylesheet Export File, the serialization properties of the run-time configuration have no effect.

`omit-xml-declaration`	HE PE EE	yes\|no	Defines whether the XML declaration should be omitted from XML output.
`standalone`	HE PE EE	yes\|no\|omit	Defines whether the XML declaration in XML output should have a 'standalone' attribute.
