2.4 Language. All the variations of the same name, no matter the language of the name, belong in the same universal group. This possibility makes it necessary to specify the language of the name. Knowing the language can tell which PS-RULES are appropriate for the parser to use, monotypic, eurotypic, or sinotypic. It may not be possible to tell from a particular spelling which language it is in, thus its language attribute could have several values. In any case the language is an attribute of a specific usage of the name.
