Henry thinks we converged on this in email on Wednesday 11 January: See
http://lists.w3.org/Archives/Public/public-xml-core-wg/2012Jan/index.html
Henry: I think we should file an issue against Polyglot about the BOM.
ACTION: Henry to file an issue against Polyglot about the BOM.
Paul: Let's call John's action finished or superseded and replace it
with Henry's action.
Henry: We didn't talk about xml:space and xml:base.
-> http://lists.w3.org/Archives/Public/public-xml-core-wg/2011Nov/0037
Henry: I think that xml:base and xml:space are allowed on MathML and SVG.
Norm: Really?
Henry: Polyglot is contradictory in some respects because I see that
xml:base is allowed.
John: There are two questions that I don't really understand. Does Polyglot
recommend anything, or does it just report facts.
Henry: It's reporting facts.
John: And what does it mean to ignore an attribute. Does that mean it
isn't reported in the DOM or does it mean that it doesn't have the
canonical effect that it's supposed to have.
Henry: In 5.2, the document says in passing that:
...there are other prefixed attributes that can be used beyond
xlink:href (such as xml:base). Polyglot markup does not declare
these prefixes via xmlns. The prefixes are implicitly declared in
XML and are automatically applied to the appropriate attributes in
HTML.
despite the fact that it says elsewhere that xml:base can't be used.
Liam: That just sounds like a bug.
John: Right, but which bug.
Henry: Section 1 lays out the facts that Polyglot reports.
Henry: I think what happens in HTML parsers is that these attributes
(xml:*) get reported as being in no namespace with a local name that
includes a colon.
Henry: The way in which this is contradictory is that the HTML5 spec
says about xml:base that it must not be used in HTML documents.
John: This may simply be version skew. That's always my first
explanation.
Henry: Wait! The HTML5 spec appears to say that xml:lang and xml:base
are allowed on MathML and SVG elements.
Some discussion of the track that Polyglot is on and whether that
makes sense.
Paul: We've only got five minutes left. We have point 4 here in
Henry's original mail. It sounds like there's some contradiction...
John: Or that it's incomplete at least.
Paul: ...so is it worth filing something?
Henry: Yes, but I should draft it first.
ACTION: Henry to draft an issue regarding xml:space and xml:base in
the Polyglot draft for WG review.

> We seem to have three choices:

> 1. allow use of the @xpointer attribute when parse=text

> We are leaning toward choice #2 which Norm will include in the

> Extending XInclude
> ------------------
> We've discussed extending xinclude to copy attributes on the
> xinclude element down to the root included element.
>
> Some issues include:
>
> 1. exactly what attributes to copy? Henry and Liam preferred to
> copy un-prefixed attributes (except those in the xinclude spec) too.
>
> Norm worries what this would mean if we add another attribute
> in the XInclude spec?
>
> Henry wants to be able to have unprefixed attributes copied
> onto the root included element.
>
> Henry: we could add a new "copy me without prefix" namespace
> to xinclude.
>
> Norm doesn't need that, but could live with it.
>
> 2. what to do about attribute conflict (error or one or the other
> wins).
>
> 3. whether we should "log" additions (e.g., via an attribute that
> says what attributes were added).
>
> At first, we didn't think this was much of a concern, but then we
> realized perhaps it was something worth considering.
>
> 4. whether we should have some way for targets to say whether they
> can be xincluded and/or, when included, have attributes added.
>
> XInclude 1.1
> ------------
> This would address the two issues discussed above:
> * @xpointer when parse="text"
> * copying attributes from the xinclude element to the root
> included element
>
> If we want to produce an XInclude 1.1, we will need an amended
> charter as indicated by Ian at
> http://lists.w3.org/Archives/Public/public-xml-core-wg/2011Dec/0014
> but we can discuss requirements now.
>
> Norm drafted an initial XInclude 1.1 requirements document at
> http://www.w3.org/XML/2012/01/xinclude-11-requirements/
Paul observes that we could publish this as a note at any time.
Paul: Norm, should we publish it?
Norm: Sure. I banged it out pretty quick, but if everyone likes it...
Paul: Ok, I think it's probably worth getting it out there.
...We should publish a requirements document before we ask for a charter
revision.
...I wonder if this is enough of a use case for improved communication.
Paul: I'll send some email and we can do a little cleanup.
