/**
 * To begin with, an abstract schema is a generic structure that could 
 * contain both internal and external subsets. An <code>ASModel</code> is an 
 * abstract object that could map to a DTD , an XML Schema , a database 
 * schema, etc. An <code>ASModel</code> could represent either an internal 
 * or an external subset; hence an abstract schema could be composed of an 
 * <code>ASModel</code> representing the internal subset and an 
 * <code>ASModel</code> representing the external subset. Note that the 
 * <code>ASModel</code> representing the external subset could consult the 
 * <code>ASModel</code> representing the internal subset. Furthermore, the 
 * <code>ASModel</code> representing the internal subset could be set to 
 * null by the <code>setInternalAS</code> method as a mechanism for 
 * "removal". In addition, only one <code>ASModel</code> representing the 
 * external subset can be specified as "active" and it is possible that none 
 * are "active". Finally, the <code>ASModel</code> contains the factory 
 * methods needed to create a various types of ASObjects like 
 * <code>ASElementDeclaration</code>, <code>ASAttributeDeclaration</code>, 
 * etc.
