The witDetail element should be regarded as a specialized type of note element; it is synonymous with <note type='witnessDetail'>, but differs in the omission of some attributes seldom applicable to notes within critical apparatus, and in the provision of the wit attribute, which permits an application to extract all annotation concerning a particular witness or witnesses from the apparatus. It also differs in that the location of a witDetail element is not significant and may not be used to imply the point of attachment for the annotation; this must be explicitly given by means of the target attribute.
