XSD schema of the REFI Project Exchange Standard
The XML schema of an imported or exported Project is a description of a type of XML document (here a .qdpx file) expressed in terms of constraints on the structure and content of .qdpx files. This means that beyond the basic syntactical constraints imposed by XML itself (a well formed xml file), each .qdpx file exported from a software should be valid according to this .xsd file.
