The max/min value element
Max/min value elements give you the ability to associate superlative phrases with columns. For example consider this example from geo.cphrase:
<column id="population" type="int" lex="population,populations,...">
<max lex="most people,most population,biggest population,..."/>
<min lex="smallest population,lowest population,least populous,..."/>
...
This allows the user to ask questions like "the cities with the most people".
