The remote-endpoint property in endpoint nodes should be mandatory,
shouldn't it? Otherwise the sensor isn't connected to anything and hardly
useful as such. The list of optional endpoint properties is a long one and
it should be documented here which ones are recognised, either as optional
or mandatory.
