FdcDataAdapterCapabilities class
Declares which query and aggregate operations an adapter can execute.
The dataset validates adapter-bound filter, sort, search, paging, and aggregate requests against these flags before dispatching work. Custom adapters should report only capabilities they can preserve semantically.
