Review result: Ready with nits

I have reviewed this document as part of the security directorate's ongoing effort to review all IETF documents being processed by the IESG.
These comments were written primarily for the benefit of the security area directors.  Document editors and WG chairs should treat these comments just like any other last call comments.

Summary: Ready with nits

[1] It is not clear to me how the Security sections of I-D.ietf-core-cocoa apply to this specification ?
[2] The security considerations section discusses I-D.ietf-lwig-6lowpan-virtual-reassembly but that document does not discuss any security considerations yet.
[3] It is not clear how the DoS attack of bogus first fragments is handled and other attacks discussed in https://tools.ietf.org/html/draft-ietf-intarea-frag-fragile-17#section-3.7 are tackled ?
[4] How does the document align with the recommendations given in https://tools.ietf.org/html/draft-ietf-intarea-frag-fragile-17#section-6 ?

Cheers,
