| SAXONICA | 
The saxon:entity-ref element is useful to generate entities such as   in HTML output. To do this, write:
<saxon:entity-ref name="nbsp"/>Note: the preferred way to produce a non-breaking space character in the output is
            simply to write   or   in the stylesheet. By
            default, with HTML output, this will be serialized as  , though the
            way it is serialized doesn't actually matter as far as the HTML browser is concerned.
         
saxon:entity-ref is permitted only in contexts where disable-output-escaping
            would be permitted: that is, when writing to a serialized output destination.
