RE: [xsl] outputting an ampersand in an attribute

You can do it with character maps but you don't need to do anything as messy
as that. You want an attribute containing the Unicode character with code
point xE003 (= decimal 57347), so write

<xsl:attribute name="unicode" select="codepoints-to-string(57347)"/>

and let the serializer do its job of serializing it: that's what it's good
at.
