Converting nonextensible schemas of XML documents to RNG files

摘要

A nonextensible schema is obtained including a first content model of ANY. Based on the nonextensible schema, a compact syntax regular language for XML next generation (RNC) file is generated that includes a second content model of ANY. The second content model of ANY can correspond to the first content model of ANY. The RNC file is modified, based upon the RNC file including the second content model of ANY, so as to explicitly enumerate all semantics of the second content model of ANY as elements in the RNC file. A regular language for XML next generation (RNG) file is later generated based on the modified RNC file. Related apparatus, systems, techniques and articles are also described.
