Question about WebCAP

[Mine Sakurai <m-sakura@xxxxxxxxxxxxxxxx>]

Hi, 

I have a question about WebCAP(draft-ietf-pkix-webcap-00.txt). 

In the WebCAP draft,

|4.3.  GETCERT
|    The GETCERT method retrieves certificate(s) from the CA repository
|    specified by the Request-URI.  All CAP compliant resources MUST sup-
|    port the GETCERT method and the getcert XML element along with all
|    XML elements defined for use with that element.
|
|    A client SHOULD submit a getcert XML element in the body of the
|    request method describing what information is being requested.
|
|    All servers MUST support returning a response of content type
|    text/xml that contains a multi-status XML element that describes the
|    results of the attempts to retrieve the various certificates.
 ...

When retrieving multiple certificates, is it assumed to send a
GETCERT request even if the certificates are issued by different CAs?

If it is assumed, which kind of multi-status response is returned 
when the CAP server can't get all the certificates? 

regards,
