E-17. Version 9.0 of Acrobat and Adobe Reader do not implement the value of
A
(annotation array order) of
the
Tabs
entry of the page object.
E-18. Acrobat Pro and Acrobat Pro Extended while in portable collection editing mode use the combination
of
ID
,
Locale
, and
Version
to uniquely identify a navigator. This behavior allows the application to
determine that the navigator embedded in a collection is the same as a navigator description stored on
hard disk. IDs can be human-readable or a URN based on a machine-generated GUID, as long as they
are likely to be unique. GUIDs are defined in RFC4122,
A Universally Unique Identifier (UUID) URN
Namespace
, listed in the
Bibliography
.
E-19. For version 9.0, a PDF viewing application loads the navigator found in the PDF file, no matter what
navigators are available.
In addition to loading the navigator in the PDF file, a portable collection authoring application—
Acrobat Pro or Acrobat Pro Extended—loads the navigator with the highest version number when it
finds more than one with the same ID and locale. Acrobat, in authoring mode, usually shows the PDF
file's navigator as well as all the loaded navigators. If one of the loaded navigators matches the PDF
file's navigator (ID, version, locale), only one copy is shown in the navigator list. If the PDF file's
navigator is newer (higher version number), only it is shown. If the PDF file's navigator is older, both are
shown, with the loaded navigator marked as
new
.
E-20. For Acrobat 9.0, if a
WKT
string is present, it is used to specify the coordinate system. If an
EPSG
code is
present, it shall be consistent with the
WKT
string. If no
WKT
string is present, the
EPSG
code is used to
specify the coordinate system.
