           Provenance information is not of itself guaranteed to be authoritative or correct. Trust in provenance information must be determined separately from trust in the original resource. Just as in the web at large, it is a user's responsibility to determine an appropriate level of trust in any other resource; e.g. based on the domain that serves it, or an associated digital signature. (See also <a href="#security-considerations" class="sectionRef"></a>.)
