For example:

  >
*$myConcat := function($s1, $s2)*  >
*{ *>      *$s1 || '&' || $s2*
    *}*>
*return*
*   $myConcat('month', 'august')*

produces
  *month&august*


produces:
*month&august*

Gmail is tricky when one wants to highlight text, as I did in the previous
email -- it seemed good white on dark blue ... One can still select it
above and it will show :)

There is nothing to be escaped in the above expression! This is XPath,
not XML.


Well, $makeElement('menu', 'bangers&mash') is going to fail.


Only because we are constructing an XML element. If there are no
additional limitations imposed, one can use the '&' character without
escaping.

For example:





*$myConcat := function($s1, $s2){ $s1 || '&' || $s2}*

*return*
*   $myConcat('month', 'august')*

produces

   *month&august*

To summarize, any implementation of an element() function must throw an
error if passed unescaped ampersand(s), not just the XPath function
implementation.
