SSPROP_STREAM_XMLROOT

Type: VT_BSTR R/W: Read/Write

Description: The result of a FOR XML query may not be a well-formed document. When this property is specified, the result of a ‘select … for XML’ query is wrapped in the root tag provided by this property to return a well formed XML document. If the query is executed in the browser it may cause the browser to display parser errors when loading the result. To avoid the error, SQL ISAPI supports the keyword ROOT. This keyword maps to SSPROP_STREAM_XMLROOT property.
