In order to have a workable proposal, the set was arbitrarily frozen at around the time it was first submitted to WG. ll additional candidate characters for encoding that were found during the lengthy review phase for the original proposal were tracked separately, in order to confine the more tentative characters to a small manageable set. In the meantime, many, if not most of the characters in this secondary, but much smaller set have been confirmed. n ad-hoc group consisting of the authors of this document, with input from Michael verson, Ken Whistler and Murray Sargent have narrowed the candidate characters down to the list presented here and provided suggested names and annotations. ormat of this document While the format of this document follows that of a Unicode character names list, no code locations are suggested and many of the annotations are provided mainly for the readers and reviewers of this document; they are not intended to become part of the standard. few already existing characters are shown for purposes. These are clearly noted in the list of names; there is no intention to request duplicate encodings for them. In some cases compatibility mappings with novel tags can be found in the names list. These are indications of glyphic or semantic relations between characters, not as formal decompositions. In the final standard they would be replaced by simple cross-references.
