Modello should be able to generate and handle enumerations.
[model]: Add reading of <enumeration> tags. Be able to create integer and string type enumerations.
Integer style enumerations look like this:
public final static FOO = 1;
public final static BAR = 2;
String style enumerations look like this:
public final static FOO = "foo";
public final static BAR = "bar";
[java]: Enumeration classes like  should be generated. The model should only return instances of the generated enumeration class.
[xpp3]: When reading and writing enumeration fields serialize and deserialize the enumeration.
[jpox]: Same as for [xpp3].
[xml-schema]: I'm pretty sure xml-schema can handle something like this.
[xdoc]: Add documentation support for the different enumeration elements.
