XOP/MTOM specs remaining problems

Dear all,

I went throught the last versions of both the XOP and MTOM 
specifications to check for any unresolved problems in them. Here is a 
list of them with proposals for solving them.

Hervé.

--- XOP ---
2.1 MIME Multipart/Related XOP Packages
Issue:
The media type for the root part of the package is TBD.

Proposal:
I think that the media type can vary depending on the type of the 
original XML Infoset. Therefore, I propose to remove any reference to a 
media type for the root part of the package.

4.2 Interpreting XOP Packages
Issue:
Nothing is said about what to do when the reconstruction of the XML 
Infoset fails, or if the XOP Package is incorrect while still allowing a 
reconstruction of the XML Infoset (e.g., xop:Include has a child element).

Proposal:
States that any failure is to be handled in an implementation dependant way.
States that any non fatal error may be ignored at the discretion of the 
implementation.


--- MTOM ---
1.2 Relation to other specifications
Issue:
Relation with SOAP 1.2 Attachment Feature is not clearly defined.

Proposal:
WG should decide what is the relation with this document.

---
1.2 Relation to other specifications
Issue:
Relation with SOAP Attachment Requirements is that no reconciliation has 
been done.

Proposal:
Change this to state that MTOM fulfills SOAP Attachment Requirements.

3. An Optimized MIME Multipart Serialization of SOAP Messages

Issue:
This section does not reference XOP 2.1 MIME Multipart/Related XOP 
Packages section while it builds upon it.

Proposal:
Change 3.2 and 3.3 text to refer to XOP 2.1 MIME Multipart/Related XOP 
Packages section instead of RFC 2387.
Add a reference to this section in 3.1 (this is already proposed in 
rec20 and rec22 resolution).

3.3 Deserialization of a SOAP message
Issue:
Nothing is said about what happens when the SOAP message can not be 
deserialized.

Proposal:
States that consequence of reconstruction failure is 
application/specification dependant.

---
4.3.2 Receiving a SOAP message
Issue:
How to recognize a message serialized using XOP?

Proposal:
States that this is realized by using the media-type, i.e., the whole 
message should be a mime/multipart-related package with a root part of 
type application/soap_xop+xml.
