Table 97 – Entries in a Reference Dictionary

Key

Type

Value

F

file specification

(Required) The file containing the target document.

Page

integer or text string

(Required) A page index or page label (see 12.4.2, "Page Labels" ) identifying the page of the target document containing the content to be imported. This reference is a weak one and may be inadvertently invalidated if the referenced page is changed or replaced in the target document after the reference is created.

ID

array

(Optional) An array of two byte strings constituting a file identifier (see 14.4, "File Identifiers" ) for the file containing the target document. The use of this entry improves an reader’s chances of finding the intended file and allows it to warn the user if the file has changed since the reference was created.
