The QPR XML file contains exactly one Model XML element, which contains all the QPR XML child elements. Model may contain some XML attributes that are related to localization, e.g. decimal separator or short date format.
When importing an XML file, the file must contain the xmlns="www.qpr.com" attribute under the Model element. The XML export generates this attribute automatically, but when importing XML that has not been generated by a QPR product, it is necessary to verify that the attribute is there. The import will not succeed without the attribute. For more information about the correct schema, refer to section QPR XML Schema.
