Simple accessibility fixes to frames HTML doc output
----------------------------------------------------

                 Key: DERBY-5136
                 URL: https://issues.apache.org/jira/browse/DERBY-5136
             Project: Derby
          Issue Type: Sub-task
          Components: Documentation
    Affects Versions: 10.7.1.1
            Reporter: Kim Haase
            Assignee: Kim Haase


The frames versions of the HTML manuals have some accessibility errors that are quite easy
to fix, involving the index.html file and section heads.

The index.html file for the frames version has several errors:

1) The <html> element lacks a lang attribute (lang="en" in this case).

2) The <frameset> element lacks a <noframes> element telling people with browsers
that don't support frames where to find an alternative version of the documentation. We can
point them to the single-file HTML manual.

3) The <frameset> and <frame> elements require title attributes.

It is possible to fix these issues fairly easily by providing a modified version of the DITA-OT1.1.2.1/resource/index.html
file and then by making some additional edits to the init and html.dita tasks in the build.xml
file.

The documentation also violates the rule that heads must appear in order. The topics in the
Derby documentation generate only two HTML head tags, <h1> for the topic title and <h4>
for sections. Sections cannot be nested in DITA. 

It is possible to fix this problem by providing a modified version of the DITA-OT1.1.2.1/xsl/xslhtml/dita2htmlImpl.xsl
file that specifies the use of <h2> tags instead of <h4>. Section heads are always
generated with the "sectiontitle" class, which is specified in the .css files, so the output
seems to look the same with either head in a browser that supports stylesheets.

I plan to file a patch for this task tomorrow.
