Stm
stream
(Optional; must be an indirect reference)
The content stream containing the
marked-content sequence. This entry should be present only if the marked-con-
tent sequence resides in a content stream other than the content stream for the
page—for example, in a form XObject (see Section 4.9, “Form XObjects”) or an
annotation’s appearance stream (Section 8.4.4, “Appearance Streams”). If this en-
try is absent, the marked-content sequence is contained in the content stream of
the page identified by
Pg
(either in the marked-content reference dictionary or
in the parent structure element).
(Optional; must be an indirect reference)
The PDF object owning the stream
identified by
Stm
—for example, the annotation to which an appearance stream
belongs.
(Required)
The marked-content identifier of the marked-content sequence with-
in its content stream.
