Using Word's XML Structure to Store My Own Information

When you start editing a file with MS-Word or LibreOffice, there are locking systems preventing several users to edit the same file at the same time.

The examples might not work properly on the local file system due to security settings in your browser. Please use a real webserver

About Office File Validation

Office File Validation helps detect and prevent a kind of exploit known as a file format attack or file fuzzing attack. File format attacks exploit the integrity of a file, and they occur when someone intentionally modifies the structure of a file to add malicious code. Usually the malicious code is run remotely and is used to elevate the privilege of restricted accounts on the computer. As a result, attackers could gain access to a computer that they did not previously have access to. This could enable an attacker to read sensitive information on the computer’s hard disk drive or install malware, such as a worm or a key logging program. The Office File Validation feature helps prevent file format attacks by scanning and validating files before they are opened and then notifying the user if the file may have been compromised.

To validate files, Office File Validation compares a file’s structure to a predefined file schema, which is a set of rules that determine what a readable file resembles. The file does not pass validation if Office File Validation determines that a file’s structure does not follow all rules that are described in the schema.

To run Office File Validation on either Office 2003 or Office 2007 you must first apply the Office File Validation files to the computers that are running either Office 2003 or Office 2007.
