Created umbrella ticket for hard coded issue. I will add sub-tasks as I can. Please help if you see one that is missed.

It would be the same via HTML or Javascript, either one would need access to the Locale, which comes from the Sakai server. I think this all should go into a separate ticket so its not lost, and we can track the appropriate fixes for all tools.

If the lang attribute is being set in a template, and is hard to update. Perhaps it would be best set using JavaScript. I'd set it as soon as possible. The following seems to work in IE and FF in my limited tests:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<title>Setting lang attribute on the HTML element using JS Test</title>
</head>
<body class="portalBody">
<script type="text/javascript">
document.body.parentNode.setAttribute('lang','es');
document.body.parentNode.setAttribute('xml:lang','es');
</script>
<h1>Setting lang attribute on the html attribute using js</h1>
</body>
</html>

It seems that there is also a Content-Language meta element coming in from includeStandardHead.vm that sets the language. I'm not sure if this is referenced by adaptive technologies...
I found this when I viewed the source:
<!-- START from includeStandardHead.vm -->
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8" />
<meta http-equiv="Content-Style-Type" content="text/css" />
<meta http-equiv="Content-Language" content="en_US" />
The default human language doesn't appear to be set in any of the Samigo document contexts.
This is critical especially for international students who use screen-reading software. Their O/S, browser, etc. may default to a different language and the adaptive technology will mispronounce all of the words (for instance, trying to read english text as if it were spanish, french, etc.). This would be a great source of user annoyance which is especially unwelcome while taking an assessment.
Most Sakai tools declare the default human language in the <html> tag. For example, the portal does like so:
<html xmlns="http://www.w3.org/1999/xhtml" lang="en" xml:lang="en">
This issue is a failure to meet WCAG 2.0 SC 3.1.1 Language of Page: The default human language of each Web page can be programmatically determined. (Level A)
WCAG 2.0 SC 3.1.1 is described here: http://www.w3.org/TR/UNDERSTANDING-WCAG20/meaning-doc-lang-id.html
