When the cayenne documentation states it only supports sequences for Oracle,
it's only natural to think that the seven phrases used by Oracle to describe
sequences (INCREMENT BY, STARTS WITH, MINVALUE, MAXVALUE, CYCLE, CACHE SIZE,
ORDER) mean the same thing when Cayenne talks about sequences.
Can we update the documentation to make it less confusing? Maybe point out
that "cache size" means something different if you're talking about an
"Oracle sequence" than if you're talking about a "Cayenne representation of
a Oracle sequence"?
And change the default Oracle values to the same defaults values that Oracle
uses?
