otocol specifications only) In this context, some properties of the UCS become relevant and have to be addressed. It should be noted that such properties also exist in legacy encodings, and in many cases have been inherited by the UCS in one way or another from such legacy encodings. In particular, these properties are:
* Choice of binary encoding forms (UTF-8, UTF-16, UCS-4) Variable length encodings (e.g. due to the use of combining characters, surrogates,...)
* Duplicate encodings (e.g. precomposed vs. decomposed)
* Control codes for various purposes (e.g. bi-directionality control, symmetric swapping, This means that in order to insure consistent behavior on the WWW, some additional specifications, based on the UCS, are necessary. This document is written as part of the work of the I18N WG to provide internationalization guidelines for the authors of W3C specifications. Because of the importance of consistent behavior for the WWW, it should be expected that the resulting guideline components will become mandatory for W3C specifications.
1.2 Potential users of the resulting specification
The specification that will be developed based on this document have a very wide range of potential users, which are listed below in three categories. A need for specifications in the areas addressed by this document has directly been expressed by (in particular at the "Query Language Meeting" in April 1998 in Brisbane) the following W3C Working Groups or specifications:
* The XML activity, for XPointer XSL (Extensible Style Language)
* RDF (Resource Description Framework) Model and Syntax Within the W3C, it may in addition be useful for:
Outside of the W3C, it may in addition be useful for things such as:
