Minor issue on http://www.ietf.org/internet-drafts/draft-duerst-mailto-bis-01.txt

Hi Martin, cc'ing to uri@w3.org,

I saw a minor issue in  
http://www.ietf.org/internet-drafts/draft-duerst-mailto-bis-01.txt:

The security considerations of [RFC3986], [RFC3490], [RFC3491], and also  
apply. [RFC3987]

should mayb be

The security considerations of [RFC3986], [RFC3490], [RFC3491], and  
[RFC3987] also apply.

Also, I am wondering about this from text from RFC 3987:
The security considerations discussed in [RFC3986] also apply to IRIs. In  
addition, RFC 3987 cites 3940/1.

Would it then not be enough to cite the security conciderations from 3987?  
Am I missing something, which is not in RFC 3987 cited from 3986 / 3490/1?  
Or is it just normal to have such overlaps in citations?

Best regards,

Felix
