# Receive notification of a skipped entity.
	#
	# This is not called for entity references within markup constructs
	# such as element start tags or markup declarations. (The XML
	# recommendation requires reporting skipped external entities.
	# SAX also reports internal entity expansion/non-expansion, except
	# within markup constructs.)
	#
	# The Parser will invoke this method each time the entity is
	# skipped. Non-validating processors may skip entities if they
	# have not seen the declarations (because, for example, the
	# entity was declared in an external DTD subset). All processors
	# may skip external entities, depending on the values of the
	# `http://xml.org/sax/features/external-general-entities`
	# and the
	# `http://xml.org/sax/features/external-parameter-entities`
	# properties.
	#
	# Parameter:
	#
	# * `name`: The name of the skipped entity. If it is a
	# parameter entity, the name will begin with `%`, and if
	# it is the external DTD subset, it will be the string
	# `[dtd]`.
