lack of clarity about the "updated" timestamp

[llemeurfr]

The spec states that "The License Document may contain ... updated [defined as] Date and time when the license was last updated".

This is structurally true, but we find no evidence in the LCP spec that updated MUST be initialized if the license is updated.

In the LSD spec, It is written that in case of return/renew, "The server must update the timestamp of both License and Status Document contained in the status and license keys of the updated object.". Here again, this is only addressing the structural issue, not the conceptual one, i.e. that the updated timestamp of the license must be ... updated.
