Collect should be added to the [SQL
documentation](https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/table/sql.html#built-in-functions)
under "Built-in Function" -> "Aggregate Functions"
Moreover, we should add `MULTISET` to the [supported data
types](https://ci.apache.org/projects/flink/flink-docs-release-1.3/dev/table/sql.html#data-types).
It would also be nice if you could open a JIRA to add support for COLLECT
to the Table API. We try to keep both in sync and it helps if we have a list of
things that need to be added.
