* Title: Protect Record
|
* Description: defines whether a sheet or workbook is protected (HSSF DOES NOT SUPPORT ENCRYPTION)
|
* (kindly ask the US government to stop having arcane stupid encryption laws and we'll support it)
|
* (after all terrorists will all use US-legal encrypton right??)
|
* HSSF now supports the simple "protected" sheets (where they are not encrypted and open office et al
|
* ignore the password record entirely).
