Comments are therefore all the more welcome.
Abstract An XML syntax for describing collections of characters is proposed. This will allow to reference character collections with URIs and thus to reference them from other protocols and formats. The main usage areas for character collections are schemas, forms, and stylesheets. Several constructs, in particular kernels, hulls, and alternatives, are provided to allow incomplete specifications and to increase network efficiency. This indicates no endorsement of its content by the W3C at this moment.
