[jira] Updated: (TAP5-457) Illegal prefix for XML namespace

     [ https://issues.apache.org/jira/browse/TAP5-457?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Folke Behrens updated TAP5-457:
-------------------------------

       Priority: Critical  (was: Major)
    Description: 
Tapestry replaces the default XML namespace alias "xml" with "ns0" and then explicitly defines "ns0" as XML namespace. This is illegal and XHTML validators like W3C's one do not accept this as valid.

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

Output becomes:
<html ns0:lang="de-DE" xmlns="http://www.w3.org/1999/xhtml" xmlns:ns0="http://www.w3.org/XML/1998/namespace">


  was:
Tapestry replaces the default XML namespace alias "xml" with "ns0" and then explicitly defines "ns0" as XML namespace. This is unnecessary and XHTML1 validators like W3C's one do not accept other namespace declarations.

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

Output becomes:
<html ns0:lang="de-DE" xmlns="http://www.w3.org/1999/xhtml" xmlns:ns0="http://www.w3.org/XML/1998/namespace">


        Summary: Illegal prefix for XML namespace  (was: XML namespace name gets redefined)
