+        Best practices for checking descriptions of images are beyond the scope

+        High quality implementation in authoring and content management tools
+        is likely to include checking for common errors, such as including a
+        description instead of a URL in the attribute, or pointing to a
+        resource that is an image or plain text, which are often poor choices
+        for a high-quality description. Additional examples of error checking
+        and repair options can be found in <a href=
