    Helper to construct opening and closing tag expressions for HTML, given a tag name. Matches
    tags in either upper or lower case, attributes with namespaces and with quoted or unquoted values.

    Example::
        text = '<td>More info at the <a href="http://pyparsing.wikispaces.com">pyparsing</a> wiki page</td>'
        # makeHTMLTags returns pyparsing expressions for the opening and closing tags as a 2-tuple
