question: public static boolean isIdent ( String str ) { return null != identHashTable . get ( str ) ; }
target:  A hash table containing all the IDENT and STRING tokens found in    the spec.  It is used for formatting comments.                      * Note: In comments, people seem to refer to the spec's strings       without the ""s, using them as if they were identifiers.  So, we    add them to the identHashTable just like identifiers.
