    Ok, I can do that instead. I was trying to consolidate the use of "id" and "expression"
in these different contexts to prevent more confusion (as you realized). Will try to come
up with something better :)

> We recently found up in HBASE-17717 that we were incorrectly setting an ACL on our "sensitive"
znodes after the output of {{getACL}} on these nodes didn't match what was expected.
> In referencing the documentation about how the {{auth}} ACL scheme was supposed to work,
it was unclear if it was a ZooKeeper bug or an HBase bug. After reading some ZooKeeper code,
we found that it was an HBase bug, but it would be nice to clarify the docs around this ACL
scheme.
