35 * Multi-pass working schema creation
37 * - shallow copy initial schema supplied
38 * - create a working schema in multiple passes
39 * until all objects are resolved
40 * Working schema is a schema with Attributes, Classes
41 * and indexes, but w/o subClassOf, possibleSupperiors etc.
42 * It is to be used just us cache for converting attribute values.
