 It is necessary to allow HTML primitive characters such as "×" in
 string attributes, e.g.

  <input type="image" src="delete.gif" alt="&times;" name=...>

 However, passing "&times;" to strAttr results in an encoded string
 "&amp;times;", which doesn't
 render the nice little x we need.  Attached is a patch to add an htmlAttr
 function so we can say

  input ! [strAttr "type" "image", strAttr "src" "delete.gif", htmlAttr
 "alt" (primHtmlChar "times")]
