We discussed this once more.  Other WG members shared
some of Paul's concerns/confusion, but we decided not
to make a WG statement.

ACTION to Paul:  Post an individual reply to www-qa 
and point the XML Core WG to that reply in case anyone
else cares to say anything further.

Richard is leaning toward changing the MUST to SHOULD
but still maintain a strong presumption of reporting
if at all feasible.

In the interest of interoperability, it is strongly
recommended that xml:id errors not be silently ignored.

CONSENSUS:  We will change the must to a should, remove
"to the application", and add the above "interest of
interoperability" sentence.

> 9.  absolutivity of [base URI]
>     Norm has asked a question about the absolutivity of [base URI]:
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Feb/0031
> 
> We discussed this at our f2f:
> http://www.w3.org/XML/2005/02/xml-f2f-20050303-minutes.htm#base-uri
> 
> We have CONSENSUS that base URIs are always absolute.

> Then we had a further issue about base URIs in the infoset.
> 
> DV asks if it's always possible to make a relative URI absolute.
> Consider a relative xml:base URI in a stream that has no base URI.
> 
> DV thinks his implementation doesn't expect the base URI to be
> absolute.

Richard says that, in this case, the Infoset does not define
a base URI.  All base URIs defined by the Infoset are absolute,
but we say nothing about a base URI defined by an application.

> 
> There is agreement that in the case where the base URI of an infoset
> is absolute, that all base URI properties in that infoset should be
> absolute.
> 
> Richard sent email to www-tag on this:
> http://lists.w3.org/Archives/Public/www-tag/2005Apr/0077
about possible differences between what 2396 and 3986 say
about base URIs.
> 
> ACTION to Henry, Norm:  Ensure the TAG is aware of this thread
> and let us know if they have anything to say.

ACTION to Henry, Norm continued.

> 
> 11.  XInclude, schema validity-assessment, xml:base and xml:lang
> 
> Henry kicked this off at:
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2005Apr/0039
> 
> XInclude requires xml:base fixup with adds xml:base
> attributes to a document.  This causes problems 
> validating the result against the original schema
> if that schema doesn't mention xml:base.
> 
> Norm wants the XML Schema group to have a mode that
> says "just assume all xml:* attributes are okay".
> 
> Henry points out we even have problems with validation
> against DTDs in this case.
> 
> It was suggested that we add to the XInclude spec:
> "An XInclude processor may, at user option, suppress
> xml:base and/or xml:lang fixup."
> 
> Note, since this is "at user option" [see the XML spec
> for the defn of "at user option"], all XInclude processors
> MUST support xml:base and xml:lang fixup, but they MAY
> provide a user-specifiable option to suppress such fixup.
> 
> We have CONSENSUS to add this phrase if it satisfies
> the commentors (or as close to that as we can get).
> 
> ACTION to Henry:  Check with Mike Champion and Ashok Malhotra 
> as to whether this wording would satisfy the issue.

Progress, but still ongoing.  Henry will report next week.
