Arbortext NOTATION cgm Error

Hi everyone,

Arbortext Editor is killing the illustration Notation. After placing a cgm-file the XML structure should show up as

<!NOTATION cgm SYSTEM "cgm"> but all I can see is <!NOTATION cgm SYSTEM> (without "cgm").

Does anyone know why Arbortext is doing this?
Any help would be great! Best regards from snowless Munich!
