# defusedxml is new in 3.10.0 (3.9.4 does not require it) and is not
# optional: __init__.py imports nltk.downloader at module scope, which
# imports defusedxml.ElementTree at module scope, so a plain `import nltk`
# raises ImportError without it. Also imported the same way by
# corpus/reader/xmldocs.py and nombank.py, where upstream switched to
# defusedxml to reject entity-expansion attacks in untrusted corpus XML.
