I believe that "bean" corresponds to BeanMetaData, which extends ValueMetaData, thus is should be usable anywhere a "value" is usable.

The way it's redefined is supposed to be a restriction, i.e. you should list a subset of the elements/groups of the group you are redefining. | If you want extension, you should reference the group you are redefining in the new group and add the elements you want. | Looking at the schemas, the groups are identical in both schemas (with bean element commented out, btw). So, you can just remove the group as a child of redefine. Hm. Maybe I'll have a look at that when I get time...
