Thompson's W3C membership has expired.
Jeff Schlimmer replaced by Jonathan Marsh
Next f2f is right after the plenary
Important to attend telcons to remain in "good standing".
Please contact Jonathan if you tried to dialin and could not, because of issues with Zakim.
JMarsh looking for reviewers for WS-CDL.
Possible issues: features, meps (different interpretation), etc.
All issues listed in agenda proposed as editorial
Umit has proposed a different order for looking at the issues
Commentator asks more liberty in specifying the expected media-type, for example "xml" would match "application/xml" and "svg+xml".
Umit thinks would provide more than what we have (intended to provide).
Umit et al. have made 3 proposals and propose to adopt proposal 2.
jmarsh: any questions or other
... any objection?
... proposal accepted
a. "Accept" not allowed
b. accept-extensions (was) not possible. Has now become possible.
<Marsh> ACTION: MTD editors implement proposal 2 for issue 260, reject other part of the comment.
c. conflict between schema type (xs:string) and RFC2616 (octects allowed)
For the latter, could change type to base64 or exclude quoted octets, or even not use RFC2616
mnot and arthur were in favor of the latter.
jmarsh points out we chose the current approach because of the difficulty of writing the correspoding schema.
anish: concern was about interop.
jmarsh: so 2616 allows some code
points not allowed in XML?
... so limited to a subset?
anish: have to specify how raw octets
can be encoded in XML
... they use quotes to delimit octet strings
roberto: agree with Jonathan, certain quotations will be invalid because of XML
jmarsh: and fewer with XML 1.1
roberto: backslash-quote will just be seen as 2 characters in XML, not an issue
anish: what about, for example, characters 129 and 133?
umit: how common are octects used in practice?
anish: same problem for content-type
amy: content-type is defined as for
MIME, so character set is restricted to ASCII (literally), so is
... in MIME, if putting non ASCII representable string, (probably) have to use base64
<anish> in rfc2045 the parameter value can be a 'token' or 'quoted-string'
jmarsh: although pointing to RFC2616,
since we are XML, the attribute value would be restricted to a
subset supported by XML
... so a little different from proposal c.3, just eliminate some characters, not all
... cannot represent raw octets that are not allowed in XML
... the XML rule would subset RFC2616
anish: by quote-octet, you mean what is inside the quote to be interpreted as octets?
<alewis> "quoted-string" in 2045 *still* excludes control characters and characters with the high bit set.
jmarsh: maybe we agree
... if you give me a list of strings compatible with 2616, and i cutandpaste in XML, only certain will work
<anish> thx amy i saw that, it is actually defined in rfc 822
<anish> but the production rules for 2616 are different from that of 2045
amy discussed how base64 is also used
agreement finally to use c.3
jmarsh/umit: not yet available, so maybe should wait until schema does the work first
<anish> IIRC (I was not part of the WG then) the wsd wg looked at a whole bunch of options and rejected NOTATIONS
<anish> i think it was david or philippe who did a evaluation of all the possible options
<dbooth> I don't think it was me.
<anish> i'll try to dig it up
<anish> i don't understand it either
anish: should ask Henry to come up with examples
umit: do we really have time to change the design completely
jmarsh: gains: special purpose constructs
umit: but inventing brand new names
asir: benefit: don't need a production rule
jmarsh: but would loose the q parameter
umit: and the parameter for the individual mediatype
jmarsh: would like to see examples from Henry, and maybe we could send him our own examples
asir: ask for a dozen mediatype example
jmarsh: feed him the examples we have allready, if any
<Marsh> RESOLUTION: Reject Henry's first proposal for 271
<Marsh> ACTION: Umit to respond to Henry asking for lots of examples on Notation solution.
jmarsh: How to distinguish between
hexBinary and base64Binary in the absence of XML schema?
... the answer is you cannot; but should you be supposed to?
umit: even if use @xsi:type?
anish: MTOM finds out because content-type of envelope is application/mtom
jmarsh: could add note saying content-type is not sufficient, information to be provided via other mechanism, for example xsi:type
umit: was my suggestion
anish: fine solution. yet another is to get rid of hexbinary, only keep binary
umit: what happens if you use mtom?
anish: mtom deals specifically with base64binary
jmarsh: consensus to add note as
... no objection
RESOLUTION: solve 266 by adding note as suggested by Jonathan above
<scribe> ACTION: Editors to add note "could add note saying content-type is not sufficient, information to be provided via other mechanism, for example xsi:type"
umit: taking Larry seriously, but would like him to understand we are not defining a protocol
jmarsh: also says that "image/*" not useful because of the variety of image types not implemented
umit: has to be able to use a range, if, for example, support jpeg and gif
jmarsh: say I implement all possible
image types, but suddendly someone adds one?
... so respond as : "not a protocol; if other issues, please post them separately"
asir: at some point there is a mapping done
umit: but not dynamic, you know in
... "*" is an extensibility point. It is up to the service to make sure it can actually handle it.
jmarsh: suggests respond as umit suggested (and see what happens). Not sure what solution he is suggesting
asir: RFC2533 is pointed out
umit: but not accepted at all, so no fruitful avenue to pursue
jmarsh: not recommendation track document; ok to go with average, understandable solution
umit: should we add more than what's in my original email?
jmarsh: yes: not dynamic, other
solutions equally bad, not recommendation track, if problems happy
to consider those
... objections to reject?
RESOLUTION: Reject issue with reasonning above
<scribe> ACTION: Umit? to respond to Larry, "not dynamic, other solutions equally bad, not recommendation track, if problems happy to consider those"
umit: suggest people read reasonning for classifying issues as editorial
