Hi all,

In this revision -04, we do the following changes:

- The major change is to decouple the multipart query service from the path
vector.
    - Instead, A capability called "allow-compound-response" is introduced
to make the property map inline.
    - The multipart query service is moved to a new document and defined
for the general cases.
- The examples section is revised to better explain the usage of the path
vector extension.
- The compatibility of the path vector extension is better clarified.
- Some general discussions are raised.

Looking forward to receiving your feedback.

Thanks,
Jensen
