           Summary: Namespace of elements made via .createElement() in XML
                    documents must be null
        QA Contact: public-webapps-bugzilla@w3.org
          Severity: minor
    Classification: Unclassified
                OS: All
          Reporter: ayg@aryeh.name
          Hardware: All
            Status: NEW
           Version: unspecified
         Component: DOM
           Product: WebAppsWG

createElement() says "Return a new element with no attributes, namespace set to
the HTML namespace, local name set to localName, and node document set to the
context object."  But this test outputs "true" in all browsers:

data:text/html,<!DOCTYPE html>
<script>
document.documentElement.textContent = 
document.implementation
        .createDocument(null, "", null)
        .createElement("x")
        .namespaceURI === null;
</script>

The namespace needs to be null if the context object is not an HTML document.
