<!--
For: database.defaultIdMethod and table.idMethod

Do not use autoincrement or sequence. They are deprecated in favor of
using native which will use the Connection pool to determine
which database it is talking to (yes, it knows that) and then use
whatever native database methodology for insert increments that it can.
Otherwise, you should use idbroker or none. none is good if you have a
table that is just a join table. idbroker is good if you want a
centralized repository for brokering out clumps of id's in a database
agnostic way.

<!--

defaultJavaNamingMethod determines how a table or column name,
from the name attribute in the xml database file, is converted to a
Java class or method name.

     nochange   - indicates not change is performed.
     underscore - Underscores are removed, First letter is
              capitalized, first letter after an underscore
              is capitalized, the rest of the letters are
              converted to lowercase.
     javaname   - same as underscore, but no letters are converted
              to lowercase.
