The CDF_SET_VALIDATE procedure ensures that file data values are validated when CDF files are opened. The purpose of data checking is to uncover security problems (buffer overflow, for example) caused by compromised CDF files. The data validation process involves extra processing overhead, so turn data checking off if the files are known to be clean and uncompromised.
