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

* REFERENCE: PG 373 Microsoft Excel 97 Developer's Kit (ISBN: 1-57231-498-2)<P>
