Let a presence container have a default presence?

[kwatsen]

A presence container is like a leaf of type boolean.
Leafs can have a default have, but not P-containers, why?

[BalazsLengyel]

IMHO explicit boolean enable/disable leafs are a better solution. We had problems with people defining properties of a protocol, not realizing, that by defining a leaf in the container (and hence the container too) they actually enabled the protocol too.

Leaf type empty have a similar problem with an implicit default of "absent".

Andy: manditory -ness is blocked by YANG list because items must be created.
