Compatibility and Implementation Notes
45. In Acrobat 5.0, file specifications accessed through
EmbeddedFiles
have a
Type
entry whose value is
F
instead of the correct
Filespec
. Acrobat 6.0
and later accept a file specification whose
Type
entry is either
Filespec
or
F
.
46. In certain situations, Acrobat 3.0 and greater do not correctly interpret file
specifications referenced by the
F
entry in Form or Image XObjects. Spe-
cifically, Acrobat ignores the file specification
EF
entry when that file spec-
ification is referenced from the XObject
F
entry.
F
entry referencing a
file specification that in turn references an embedded file. Acrobat does
not correctly interpret such file specifications.
Example H.1
13 0 obj <<
/Type /XObject

…

12 0 obj <<

/EF <</F 10 0 R>>
>> endobj
10 0 obj <<

47. If an Acrobat viewer encounters an unknown color space family name, it
displays an error specifying the name, but reports no further errors there-
after.
