This is the default behavior.

DOCUMENT

Restricts the xml instance to be a well-formed XML document. The XML data must have one and only one root element. Text nodes are not allowed at the top level.

xml_schema_collection

Is the name of an XML schema collection. To create a typed xml column or variable, you can optionally specify the XML schema collection name. For more information about typed and untyped XML, see Typed vs. Untyped XML.

The stored representation of xml data type instances cannot exceed 2 gigabytes (GB) in size. For more information, see xml Data Type.

The CONTENT and DOCUMENT facets apply only to typed XML. For more information see Typed vs. Untyped XML.
