The CLI does not document the set of supported operations. It says

Operation requests are expected to follow the format:

[node-type=node-name (, node-type=node-name)*] : operation-name ['('[name=value [, name=value]*]')']

e.g. /subsystem=web/connector=http:read-attribute(name=protocol)

but does not say what read-attribute does. Neither does it say what other operation names the CLI supports.

It should be possible to use the tool without reference to external documentation (which will likely be out of sync anyway). The tool should be self describing.
