The MS Project XML import is new and considered experimental at
this time.  Microsoft Project version 2002 and above supports saving
project files in XML format. Look for it in the MS Project
Save As dialog.  To use this import feature
you must first save your MS Project file in xml format as it will not
work with the native .mpp files.
To import the file, choose
FileImportMS Project XML.
Simply choose the file you'd like to import in the
Import a File dialog.
Please be aware of the following limitations of the import:
Properties - MS Project does
not save this into to the xml fileCalendars - not imported
due to differences in the way the two tools store the dataResource Groups - not imported
due to differences in the way the two tools store the data
