units of 16 bits. This must not be misunderstood to mean that a <a

arbitrary 16-bit units. A <a class='noxref'

character string encoded in UTF-16; this means that the

restrictions of UTF-16 as well as the other relevant restrictions

on character strings must be maintained. A single character, for

example in the form of a numeric character reference, may

correspond to one or two 16-bit units.<br />
