This is the command line in the business object that creates the xml string:
nDone = CursorToXML(cAlias, 'this.xmlRslt', 1, 0, 0, '1' )

This is the command line in the client object that reconstructs the cursor:
nRetVal = XMLTOCURSOR( _Screen.oApp.oBizObj.xmlResult, cAlias )

Adding the inline schema really speeds things up, but it doesn't fix the data type conversion issue.
