[xsl] XSLT-Numerical character entity output

["Steve Lloyd" <steve.lloyd@xxxxxxx>]

I am trying to generate an xhtml+mathml document in which the more 
esoteric maths characters are represented in the output by their decimal 
numeric entities rather than the character.
I thought I'd got the solution with the 'saxon:character-representation' 
attribute on <xsl:output>.

I use:
<xsl:output method="xml" indent="yes" encoding="utf-8" 
saxon:character-representation="decimal"/>

...but am still not getting entities on output of characters such as  #8477.

Any thoughts on where I'm going wrong?
