I have a couple of comments:

IIUC, the mechanism for retrieval of the logs is out of scope for this 
document and the corresponding mechanism document. So why is the format 
of the logs of any relevance here?

What do you mean by "incorrectly inserted"?

If this is a syntax issue, then presumably it will be dealt with as a 
syntax error of the sip message. If the standard sip handling mechanism 
is "ignore", then how will it be recognized as a "log me" marker so that 
it may be removed?

To act on this the marker must parse syntactically as a "log me" marker 
(whatever that syntax turns out to be) yet violate some semantic rule.
