Re: [xml] empty xmlns attributes

[Peter McGarvey <libxml-x packet org uk>]

I've worked out there is some sort of "namespace scoping" going on.  But
I couldn't have put it into words until you just did.  However, the fact
that my `<a href"...' wasn't comming out with the empty attribute didn't
make sense to me.

I just upgraded to 
    libxml2-2.5.3
    libxslt-1.0.26
And now it's comming out like this:

    <a xmlns="http://www.w3.org/1999/xhtml"; href="

Which is not what I would have expected.  But now I see that everyhitng
generated by my stylesheet has the correct namespace.  It's everything
in my src document which has no namespace.

So if I move the incorrectly places `xmlns' attribute in my source
document...

    <document xmlns="http://www.w3.org/1999/xhtml"; title....

and....  enlightenment.

Now the question is "How to get the stylesheet to assume a namespace if
none is given?"

But I think that would best be left for another time...

Thanks for the help.
