Is this bug a known one?

ZDM 7SP1HP5 Snapins.
After exporting a complete NAL-Object to an axt-file one is not able to
import this axt (Error when importing it partly to an existing NAL-Object
or when creating a new app based on the axt).

Error: "An error occured while attempting to convert the file."

Reason: The app does have an availability critera with an Registry rule
and a DWORD Value specified in it. This will be exported in a false way to
the xml- file. It should be converted to an ASCII sign but it will not!
