I think you mean "and" here not "or". :)  I'm not an XPath expert but I expect you can write:

    must "!derived-from-or-self(current(), 'l3vpn-svc:slaac') and !derived-from-or-self(current(), 'l3vpn-svc:provider-dhcp-slaac')" {

That would be
must "not(derived-from-or-self(current(), 'l3vpn-svc:slaac')) and not(derived-from-or-self(current(), 'l3vpn-svc:provider-dhcp-slaac'))" {

But perhaps this is a trifle simpler:
must "not(derived-from-or-self(current(), 'l3vpn-svc:slaac') or derived-from-or-self(current(), 'l3vpn-svc:provider-dhcp-slaac'))" {

[Qin]: Thank Jan for the proposed change as an XPATH expert, I prefer the second one you proposed.
