Adding documentation addresses as a _type_??

<tp>
I know, silly idea really but people do understand types in a way that they seem not to understand other YANG constructs.  And  I have seen real damage done by people not realising that an address is an example and not to be taken literally - I see documentation addresses as an example of excellent engineering.
