			4. [I-D.ietf-idnabis-protocol] is specified such that the protocol
			acts on the indvidual labels of the domain name. If an
			implementation of this mapping is also performing the step of
			separation of the parts of a domain name into labels by using the
			FULL STOP character (U+002E), the following character can be
			mapped to the FULL STOP before label separation occurs:
			* IDEOGRAPHIC FULL STOP (U+3002)
			There are other characters that are used as "full stops" that one
			could consider mapping as label separators, but their use as such
			has not been investigated thoroughly.
