RE: xmlns="" / XML to XHTML

Le mardi 13 septembre 2005 à 13:48 +0100, Michael Kay a écrit :
and b) modified the <html> Tag like this:

<html lang="de" xml:lang="de">
<xsl:attribute 
name="xmlns">http://www.w3.org/1999/xhtml</xsl:attribute>

And see there: All default namespaces are gone (Perhaps I´ve finally 
understood namespaces ;-))


No, I'm sorry, but you haven't. A namespace is not an attribute, and an
attribute is not allowed to have the name "xmlns". The spec says explicitly
(section 7.1.3) "It is an error if the [name attribute] is the string
"xmlns". If your XSLT processor accepts this stylesheet, then it has a bug
in it.

More precisely, this is an error if it accepts it and adds the namespace
declaration to the output tree (the XSLT 1.0 rec leaves the option to
implementations to silently ignore the bogus xsl:attribute in that
case).

Now, I am really curious to know why anyone would want to write:

<html lang="de" xml:lang="de">
<xsl:attribute name="xmlns">http://www.w3.org/1999/xhtml</xsl:attribute>

instead of the less verbose (and authorized)

<html lang="de" xml:lang="de" xmlns="http://www.w3.org/1999/xhtml";>
