provides an alternative value for the aspect of the markup in
question—an alternative generic identifier, transcription,
or attribute value, or the identifier of an anchor element (to
indicate an alternative starting or ending location). If an
assertedValue is given, the confidence level specified by
degree applies to the alternative markup specified by
assertedValue; if none is given, it applies to the markup
in the text.
generic identifier, attribute value, location (e.g.
indicated by a reference to an anchor element or to an
ptr element), or other appropriate alternative
value.
