+
+For example, given the above purge tree and issuing the above purge request,
+the whole document will be purged, as it contains only a single branch with a
+leaf revision `3-c50a32451890a3f1c3e423334cc92745` that will be purged.
+As a result of this purge operation, a document with
+`_id:c6114c65e295552ab1019e2b046b10e` will be completely removed from the
+database's documents's b+tree, and sequence b+tree. It will not be available
+through `_all_docs` or `_changes` APIs, as though this document never existed.
Review comment:
suggest replacing "APIs" with "endpoints"
