+.. method:: xmlparser.SetReparseDeferralEnabled(enabled)
+
+ .. warning::
+
+ Calling ``SetReparseDeferralEnabled(False)`` has security implications,
+ as detailed below; please make sure to understand these consequences
+ prior to using the ``SetReparseDeferralEnabled`` method.
+
+ Expat 2.6.0 introduced a security mechanism called "reparse deferral"
+ where instead of causing denial of service through quadratic runtime
+ from reparsing large tokens, reparsing of unfinished tokens is now delayed
+ by default until a sufficient amount of input is reached.
+ Due to this delay, registered handlers may — depending of the sizing of
+ input chunks pushed to Expat — no longer be called right after pushing new
+ input to the parser. Where immediate feedback and taking over responsiblity
+ of protecting against denial of service from large tokens are both wanted,
+ calling ``SetReparseDeferralEnabled(False)`` disables reparse deferral
+ for the current Expat parser instance, temporarily or altogether.
+ Calling ``SetReparseDeferralEnabled(True)`` allows re-enabling reparse
+ deferral.
+
+ Note that :meth:`SetReparseDeferralEnabled` has been backported to some
+ prior releases of CPython as a security fix. Check for availability of
+ :meth:`SetReparseDeferralEnabled` using :func:`hasattr` if used in code
+ running across a variety of Python versions.
+
+ .. versionadded:: 3.12.3
+
+.. method:: xmlparser.GetReparseDeferralEnabled()
+
+ Returns whether reparse deferral is currently enabled for the given
+ Expat parser instance.
+
+ .. versionadded:: 3.12.3
+
+
:class:`xmlparser` objects have the following attributes:
at :func:`iterparse`. It can be useful when you're reading a large XML document
and don't want to hold it wholly in memory.
+Where *immediate* feedback through events is wanted, calling method
+:meth:`XMLPullParser.flush` can help reduce delay;
+please make sure to study the related security notes.
