Patch v1

+/**
+ * Checks that a given attribute is correctly reflected as limited to known
+ * values enumerated attribute.

as what exactly?

+function reflectBoolean(aParameters)
+{
+  // Tests various values.
+  var valuesToTest = [

Some documentation for these objects would be nice. Also, I don't think the nested object is necessary, in particular because setContent is always true. 

+    { value: +0, stringified: 0, result: { setContent: true, setIdl: false } },
+    { value: -0, stringified: 0, result: { setContent: true, setIdl: false } },

stringified: "0"

Could you test +-Infinity as well?

+    // ES5, verse 9.2.
+    { value: { toString: function() { return "foo" } }, stringified: "foo",
+      result: { setContent: true, setIdl: true } },
+    { value: { valueOf: function() { return "foo" } },
+      stringified: "[object Object]",
+      result: { setContent: true, setIdl: true } },
+    { value: { valueOf: function() { return "quux" }, toString: undefined },
+      stringified: "quux", result: { setContent: true, setIdl: true } },
+    { value: { valueOf: function() { return "foo" },
+               toString: function() { return "bar" } }, stringified: "bar",
+      result: { setContent: true, setIdl: true } },
+    { value: { foo: false, bar: false }, stringified: "[object Object]",
+      result: { setContent: true, setIdl: true } },

These don't seem particularly interesting. The stringification is already tested in reflectString, and I don't think these would catch other bugs. Maybe a couple of variations on { valueOf: function() { return false; } }?

+  ];
+
+  valuesToTest.forEach(function(v) {
+    if (v.value === null) {
+      todo(element.getAttribute(contentAttr), v.stringified,
+         "Content attribute should return the stringified value it has been set to.");

Indentation

Maybe note bug 667856 here?

+}
+

No need for the empty line.

+++ b/content/html/content/test/forms/test_formnovalidate_attribute.html
-checkFormNoValidateAttribute('input');
 checkFormNoValidateAttribute('button');

Please move that one to test_button_attributes_reflection.html.

+++ b/content/html/content/test/test_bug546995.html

-checkAutofocusIDLAttribute(document.getElementById('i'));
 checkAutofocusIDLAttribute(document.getElementById('t'));
 checkAutofocusIDLAttribute(document.getElementById('s'));
 checkAutofocusIDLAttribute(document.getElementById('b'));

Please move these as well, so this file can go entirely. (Followup is fine for both.)

This looks good generally, but I'd like to see it once more.

"as a boolean". Did you learn how to read? :)

Indeed, setContent is always true. Though, I find it more readable like that.

For tests, I tend to think that more is better.
Added a test with "{ valueOf: function() { return false; } }".
