Clause: 9.1.2.2

Paragraph:

Category: No impact on this part

Issue: Edition 1 (Clause 8.1.2.3) clearly specified that a logical device must contain one LLN0 and one LPHD.
In Edition 2, there is no more constraint on LPHD.

Proposal: If the logical device is a root logical device, then the logical device must contain one (and only one) LPHD.
Otherwise, the logical device may contain 0..1 LPHD.

Ballot until Editor
The LPHD presence condition has been removed from 7-2 in Ed2 to 7-1 by purpose, since the Logical Device hierarchy was introduced in ed2 making the madating of LPHD in every logical device over-engineered.

See 7-1 Ed2 Clause 8.2.3.
