Subject [jira] [Commented] (DERBY-4408) missing DOCTYPE and META tags in toc.html and index.html pages
Date Thu, 21 Jul 2011 14:43:58 GMT

    [ https://issues.apache.org/jira/browse/DERBY-4408?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13069007#comment-13069007

Kim Haase commented on DERBY-4408:

Some of this is not so hard, but There are a couple of problems. First, the Apache license
is inserted after all the other processing, in the following code within the html.dita target
of the build.xml file.

        <concatfilter prepend="${basedir}/lib/apache-license-html.html"/>

So I'll have to bring the license insertion into the XSL files somehow. 

Also, getting the xmlns attribute into the html element is not trivial. If I simply insert
it into the html element in the stylesheet --

  <html xmlns="http://www.w3.org/1999/xhtml">

then in the toc frame, I get empty xmnls attributes in the meta and ul tags:

<html xmlns="http://www.w3.org/1999/xhtml" lang="en-us" xml:lang="en-us">
<meta xmlns="" content="text/html; charset=utf-8" http-equiv="Content-Type" />
<ul xmlns="">

Whereas if I do the same thing in the stylesheet for the non-toc pages, I get the empty attributes
in the head and body elements only:

<html xmlns="http://www.w3.org/1999/xhtml" lang="en-us" xml:lang="en-us">
<head xmlns="">
<body xmlns="" id="tgsactivity4"><a name="tgsactivity4"><!-- --></a>

However, if I try to create a template to set the attribute, it is completely ignored.

    <xsl:call-template name="setNamespace"/>
  <xsl:template name="setNamespace">
    <xsl:attribute name="xmlns">http://www.w3.org/1999/xhtml</xsl:attribute>

The "ant -verbose" command says,
    Warning! Illegal value used for attribute name: name

Looks like the namespace attribute is the one attribute you can't set.

At http://www.w3schools.com/tags/tag_html.asp it says that "the HTML validator at w3.org does
not complain when the xmlns attribute is missing in an XHTML document. This is because the
namespace "xmlns=http://www.w3.org/1999/xhtml" is default, and will be added to the <html>
tag even if you do not include it."

This suggests that we may not really need to add this after all?
