Many of these PSIs are recognized by Ontopia's software, and so using = them in=20 your topic maps may make these behave more gracefully with Ontopia's = software.=20 It is likely that some of these PSIs will be superseded by standardized = ones, in=20 which case these PSIs will be deprecated. Anyone should feel free to use = these=20 PSIs in their own topic maps or topic map software.
