+ * One element of an HTTP {@link Header header} value consisting of
+ * a name / value pair and a number of optional name / value parameters.
+ * <p>
+ * Some HTTP headers (such as the set-cookie header) have values that
+ * can be decomposed into multiple elements.  Such headers must be in the
+ * following form:
+ * </p>
+ * <pre>
+ * header  = [ element ] *( "," [ element ] )
+ * element = name [ "=" [ value ] ] *( ";" [ param ] )
+ * param   = name [ "=" [ value ] ]
+ *
+ * name    = token
+ * value   = ( token | quoted-string )
+ *
+ * token         = 1*&lt;any char except "=", ",", ";", &lt;"&gt; and
+ *                       white space&gt;
+ * quoted-string = &lt;"&gt; *( text | quoted-char ) &lt;"&gt;
+ * text          = any char except &lt;"&gt;
+ * quoted-char   = "\" char
+ * </pre>
+ * <p>
+ * Any amount of white space is allowed between any part of the
+ * header, element or param and is ignored. A missing value in any
+ * element or param will be stored as the empty {@link String};
+ * if the "=" is also missing <var>null</var> will be stored instead.
