>     .. and maybe . segments)

Though last week we were leaning toward attempting some
normalization, upon review this week, we were leaning
toward not attempting normalization.

Richard came up with an example where normalization
isn't feasible:
  <one>
    <two xml:base="http://example.org">
      <three xml:base="">
        <four xml:base="x/y"/>
      </three>
    </two>
  </one>

Suppose we cut out <three>, there is no value that can be 
put on <four> to get the same result.

In Richard's case, even concatenation won't give the
right result.

But all these problems only exist when the base URI 
of the document is not known.

There has been an ongoing email thread at
http://lists.w3.org/Archives/Public/public-xml-core-wg/2006May/0049 ff

Richard: If the value of the xml:base is interpreted as a URI
reference, then xml:base="" brings the base back to the
current document.  And in section 3, XML Base says that the 
value of xml:base is interpreted as a URI reference.

So xml:base="#foo" and xml:base="" both reset the base URI 
to be that of the current document.

Looks good except CR -> PER in several places.

> ACTION to Henry:  Review the situation with our upcoming 
> five PER requests and propose a schedule for any necessary

Henry suggests we do XML/NS 1.0/1.1 in one telcon on Friday
June 9th.  We should shoot for a publication date of June 14
and a PER end date of July 31.

ACTION to Henry:  Set the time for the telcon.

The WG has CONSENSUS to request PER on all four of XML/NS 1.0/1.1.

ACTION to Paul:  Send out new draft PER requests for these four.

ACTION to Francois, Richard:  Update the drafts to reflect
pubdate of 14 June 2006.  Richard should update status
sections (see those in Francois' drafts).

We discussed how to handle the implementation reports for
the new editions.  Henry suggests just leaving the IRs
as they stand.

Henry suggests some wording for the status sections
indicating that the older IRs are still valid.

Richard suggests he could write some tests for the
latest errata, so then we could have new IR documents.

ACTION to Richard:  Add some new tests and announce to
the XML Core list.
