Regarding bug 309242
I think a better way to add the batch-fetch-size support to the
schema would be to add a batch-fetch complex type that includes type
attributes. This would align with the BatchFetch annotation and
the batch-fetch-type and batch-fetch-size elements from being
multiple mappings in the schema.
Also, what were your thoughts on not adding functionality to the
basic-collection and basic-map elements in 2.1 since those are now
