Ken thanks for your quick answer
In my case I have a Kyocera running an Eudora browser that
does not work
well with the amperson and I need to generate "&" instead of "&".
There are ways of generating invalid HTML if you really need to, which it
seems you do.
In Saxon 6.x there is an extension saxon:disable-output-escaping on
xsl:attribute
In Saxon 8.x you can use character maps: assign some private use character
to the meaning "unescaped ampersand", and map it to an ampersand as the
output string.
Please also raise a bug report with the supplier of this broken browser.
