//  Class LDOMString
//  Represents various object types which can be mapped to XML strings
//
//  LDOMString is not an independent type: you must be sure that the owner
//  LDOM_Document is never lost during the lifetime of its LDOMStrings - for
//  that it is necessary to keep at least one LDOM_Document or LDOM_Node alive
//  before all LDOMString's (LDOM_AsciiDoc type) are destroyed.
