DXL Import fails

When I do DXL import using Notes client apis I get the following error. This happens even in 8.5 clients too. Please see the error

<?xml version='1.0'?>No character data is allowed by content modelNo character data is allowed by content modelNo character data is allowed by content modelElement 'par' is not valid for content model:'(font?,(text|code))'Element 'section' is not valid for content model:'EMPTY'Element 'pardef' is not valid for content model:'EMPTY'

Please let me know what this is.
