// This is an internal helper class which walks the tree for the ValidateIdentifiers API in the CodeGenerator. For the most part the generator code has been copied and
// turned into validation code. This code will only validate identifiers and types to check that they are ok in a language
// independent manner. By default, this will not be turned on. This gives clients of codedom a mechanism to
// protect themselves against certain types of code injection attacks (using identifier and type names).
// You can pass in any node in the tree that is a subclass of CodeObject.
