// -------------------+--------------------------------------------------------------------------
|
|
// Application | The name of the application that created this document.
|
|
// |
|
|
// ScaleCrop | Indicates the display mode of the document thumbnail. Set this element
|
|
// | to 'true' to enable scaling of the document thumbnail to the display. Set

|
|
// | 1 - Document is password protected.
|
|
// | 2 - Document is recommended to be opened as read-only.
|
|
// | 3 - Document is enforced to be opened as read-only.

|
// | element to 'true' to indicate that hyperlinks are updated. Set this
|
|
// | element to 'false' to indicate that hyperlinks are outdated.
|
|
// |
|
|
// HyperlinksChanged | Specifies that one or more hyperlinks in this part were updated

|
// | exclusively in this part by a producer. The next producer to open this
|
|
// | document shall update the hyperlink relationships with the new
|
|
// | hyperlinks specified in this part.
|
|
// |
|
|
// AppVersion | Specifies the version of the application which produced this document.
