XML Schema Instance Attributes
The XML Schema definition language (XSD) defines four attributes for use in XML instance documents. These attributes are in the https://www.w3.org/2001/XMLSchema-instance namespace. These attributes are often prefixed with xsi, although any prefix can be used and mapped to the https://www.w3.org/2001/XMLSchema-instance namespace URI.
