Documentation: toc.html files need lang attribute
-------------------------------------------------
Key: DERBY-5205
URL: https://issues.apache.org/jira/browse/DERBY-5205
Project: Derby
Issue Type: Sub-task
Components: Documentation
Affects Versions: 10.8.1.2
Reporter: Kim Haase
Assignee: Kim Haase
Priority: Minor
The generated toc.html file in the frameset has an html tag that is missing a lang attribute.
The lang attribute is required to make the TOC file accessible.
The toc.html file is generated from the XSL stylesheet DITA-OT1.1.2.1/xsl/map2htmtoc.xsl.
It is possible to edit this stylesheet so that it generates the appropriate lang attribute
the same way the DITA-OT1.1.2.1/xsl/xslhtml/dita2htmlImpl.xsl file does for the topic files.
The modified file needs to be put in the lib directory, and the build.xml file needs to be
modified to copy it into the correct directory.
The file needs to call a template similar to the setTopicLanguage template in dita2htmlImpl.xsl;
I've renamed it setTocLanguage. The file needs to import common/dita-utilities.xsl, which
defines the getLowerCaseLang template. These are the changes from the original map2htmtoc.xsl.
