Remarks
For the <ExtendedAttributes> collection Two pieces of data are necessary; a pointer back to the extended attribute table which is specified either by the unique ID or the Field ID, and the value which is specified either with the value, or a pointer back to the value list.
Note When loading a project stored as XML data, a maximum of 5000 <ValueList> elements and 128 <Indicators> elements will be recognized by Microsoft Office Project 2003. All others will be ignored.
