John decided now that there are no problems here.
Issue closed.

The issues remain only when the document doesn't have
a base URI.  And the key thing for C14N is just to get
the same result all the time.  So there seem to be three
possibilities when the document has no base URI:

1.  delete all xml:base attributes
2.  just do simple concatenation with xml:base attributes
3.  do concatenation with some normalization (e.g., handling
    .. and maybe . segments)

Paul argues for choice 2--"simple concatenation" but
no normalization.

Jose worries that another process might see a non-normalized
xml:base attribute and try to normalize it and then you
won't get the same C14N results.

Richard then asks what happens when a fragment without
absolute base URIs gets embedded in another document.

Konrad prefers to do .. normalization to minimize the
number of different canonicalizations for what should
be equivalent documents.

ACTION to Richard:  Review the new suggested wording
in Konrad's email at

ACTION to Jose and Konrad:  Develop suggested wording
for the remaining edge cases.

Richard points out that the XML Base spec isn't clear
what should happen with xml:base="", and we might need
to issue an erratum to XML Base for this.

ACTION to Richard:  Review XML Base and make a suggestion
as to what we should do to that spec regarding xml:base="".

ACTION to Henry:  Review and comment on the PER requests.

ACTION to Henry:  Review the situation with our upcoming 
five PER requests and propose a schedule for any necessary
steps (telcons, pubdates, etc.).  FWIW, Paul will be unavailable
June 5-7 and 14-23, but his presence shouldn't be a sin qua non
for anything here.

Henry met with Chris yesterday, and Chris is going to
take the XML CG input outlined at
and produce another draft.

Chris and Henry also are backing "xpointer scheme" down 
from "registered" to "pending" in the registry.

We will now await a new draft from Chris.
