Using xml:lang

[Pierre Attar <pa...@tireme.fr>]

Hi,

It seems that I have a problem with Xalan 1.1 (xerces 1.1.2.) while 
validating documents regarding to its DTD when the DTD is using the 
xml:lang attribute.

Using the XML and Namespace recommendation,
"The namespace prefix, unless it is xml or xmlns, must have been declared 
... The prefix xml is by definition bound to the namespace name 
http://www.w3.org/XML/1998/namespace."
I try :
<!DOCTYPE TEST [
<!ELEMENT TEST (#PCDATA)>
<!ATTLIST TEST
xml:lang NMTOKEN 'fr'
 >
]>
<TEST xml:lang="fr">Some text in french</TEST>

The answer from Xerces is :
[Error] attribute xml:lang not found in element type TEST
Parser error: Attribute "xml:lang" must be declared for element type "TEST".



Even if I add a namespace declaration
<!DOCTYPE TEST [
<!ELEMENT TEST (#PCDATA)>
<!ATTLIST TEST
xml:lang NMTOKEN 'fr'
 >
]>
<TEST xmlns:xml="http://www.w3.org/XML/1998/namespace" xml:lang="fr">Some 
text in french</TEST>
It does not work.

The only thing that does work is well formed validation, with no doctype :
<?xml version="1.0" encoding="utf-8"?>
<TEST xml:lang="fr">Some text in french</TEST>

Someone test this using rxp on the xml-dev list and it works :
"rxp successfully validated your example."


Any idea ? I'm usin the command line base of xalan, with something like :

java org.apache.xalan.xslt.Process -in myfile.xml -xsl mystyle.xsl -out 
myoutput.xml


Regards,
Pierre

Yes, that is a bug in namespace binding in XMLDTDScanner, it has been fixed
in the CVS.
