Re: rfc4310bis 03 AD Feedback

Is there anyone out there supporting or planning on supporting the client
specified maxSigLife.  In looking into this in more detail if this attribute
were supported, doesn¹t it make more sense for it to be an attribute outside
the dsData or keyData, since it applies to the domain¹s RRSIG and not to an
individual DS?  This means that it¹s an attribute of the domain and not of
the DS.  Since we¹re not worried about backward compatibility any longer
with the change in the URI we¹re open to remove or move this element.  Any
thoughts to this?

Please forgive my ignorance, as I wasn't around when 4310 was written.

What's the rationale for giving the child _any_ say in the DS record
signature lifetimes as presented in the parent zone?

kind regards,
