//
//  This file defines the XML statement database structure as written in 
//  <TranslationUnit> sub-nodes of the XML document. 
//  The semantics of the attributes and enums are mostly self-documenting
//  by looking at the appropriate internally used functions and values.
//  The following macros are used:
//
//  NODE_XML( CLASS, NAME ) - A node of name NAME denotes a concrete 
//  statement of class CLASS where CLASS is a class name used internally by clang. 
//  After a NODE_XML the definition of all (optional) attributes of that statement 
//  node and possible sub-nodes follows.
//
//  END_NODE_XML - Closes the attribute definition of the current node.
//
//  ID_ATTRIBUTE_XML - Some statement nodes have an "id" attribute containing a 
//  string, which value uniquely identify that statement. Other nodes may refer 
//  by reference attributes to this value (currently used only for Label).
//
//  TYPE_ATTRIBUTE_XML( FN ) - Type nodes refer to the result type id of an
//  expression by a "type" attribute. FN is internally used by clang.
// 
//  ATTRIBUTE_XML( FN, NAME ) - An attribute named NAME. FN is internally 
//  used by clang. A boolean attribute have the values "0" or "1".
//
//  ATTRIBUTE_SPECIAL_XML( FN, NAME ) - An attribute named NAME which deserves 
//  a special handling. See the appropriate documentations. 
//
//  ATTRIBUTE_FILE_LOCATION_XML - A bunch of attributes denoting the location of
//  a statement in the source file(s).
//
//  ATTRIBUTE_OPT_XML( FN, NAME ) - An optional attribute named NAME. 
//  Optional attributes are omitted for boolean types, if the value is false, 
//  for integral types, if the value is null and for strings, 
//  if the value is the empty string. FN is internally used by clang.
//
//  ATTRIBUTE_ENUM[_OPT]_XML( FN, NAME ) - An attribute named NAME. The value
//  is an enumeration defined with ENUM_XML macros immediately following after 
//  that macro. An optional attribute is ommited, if the particular enum is the 
//  empty string. FN is internally used by clang.
//  
//  ENUM_XML( VALUE, NAME ) - An enumeration element named NAME. VALUE is 
//  internally used by clang.
//
//  END_ENUM_XML - Closes the enumeration definition of the current attribute.
//
//  SUB_NODE_XML( CLASS ) - A mandatory sub-node of class CLASS or its sub-classes.
//
//  SUB_NODE_OPT_XML( CLASS ) - An optional sub-node of class CLASS or its sub-classes.
//
//  SUB_NODE_SEQUENCE_XML( CLASS ) - Zero or more sub-nodes of class CLASS or 
//  its sub-classes.
