Subject: Relationship between SAN and IAN?

Hello Folks,

I have a query for clarification and needs your views.
Let us consider there are two certificates A and B (part of the certification path). 
  a.. If A is issuer of B and there is SubjectAltName extension present in A and IssuerAltName in B and value of SubjectAltName in A is "URL=http://www.testservername.com". Is there any requirement in RFC 2459 or 3280 or some where else for IssuerAltName value (if present) in B. I mean in this case IssuerAltName value must contain "URL=http://www.testservername.com"? 
  b.. Similar query for SubjectKeyIdentifier and AuthorityKeyIdentifier that if SubjectKeyIdentifier value is of 60-bit length in A. Is RFC allows to put AuthorityKeyIdentifier value of 160-bit length in B?
Regards,
