  * tokens do not have a common base class. All tokens need to have a field
  * with the word id that points to an entry in the `word` database table
  * but otherwise the information saved about a token can be very different.
- *
- * There are two different kinds of token words: full words and partial terms.
- *
- * Full words start with a space. They represent a complete name of a place.
- * All special tokens are normally full words.
- *
- * Partial terms have no space at the beginning. They may represent a part of
- * a name of a place (e.g. in the name 'World Trade Center' a partial term
- * would be 'Trade' or 'Trade Center'). They are only used in TokenWord.
