// -------------------+--------------------------------------------------------------------------
|
||||
// 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

// | this element to FALSE to enable cropping of the document thumbnail to
|

// | show only sections that will fit the display.
|
||||
// |
|
||||
// DocSecurity | Security level of a document as a numeric value. Document security is
|
||||
// | defined as:
|
||||
// | 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.

// | 4 - Document is locked for annotation.
|
||||
// |
|
||||
// Company | The name of a company associated with the document.
|
||||
// |
|
||||
// LinksUpToDate | Indicates whether hyperlinks in a document are up-to-date. Set this
|
||||
// | 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// | element to FALSE to indicate that hyperlinks are outdated.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.

// | The content of this element shall be of the form XX.YYYY where X and Y

// | represent numerical values, or the document shall be considered
