Oops, I forgot one comment.

5) Comment: Length of URIs.

I remember a somewhat long discussion on xml-dist-app about that and
am still unsure about what we should say, but the following statement
struck me[8]:

|   SOAP does not place any a priori limit on the length of a URI. Any
|   SOAP node MUST be able to handle the length of any URI that it
|   publishes and both SOAP senders and SOAP receivers SHOULD be able to
|   deal with URIs of at least 2048 characters in length.

Even though the URI specification doesn't specify any limit on the
length of a URI, the HTTP spec does provide a URI too long error
code[9].

2kB is identified here as a reasonable value to be able to handle.
This seems to be an architectural issue, a Web services one as well as
a Web one. I am afraid that such a statement will have a big impact on
software designed.

I think that I would be more comfortable by saying that software
should be able to handle URIs of arbitrary length, and that a
2kB-length is seen _in SOAP's context_ as a minimum value to support.

Regards,

Hugo
