Subject: How to make REXML respect &nbsp; (in 1.9)

Rubies:

This fails on the second line...

    REXML::Document.new('<b>&amp;</b>')
    REXML::Document.new('<b>&nbsp;</b>')

...with Undeclared entity '&nbsp;'

If I make that real XHTML, with a DOCTYPE and a html xmlns="...xhtml", it 
still fails.

I fixed the &nbsp; itself by adding [<!ENTITY nbsp " ">] to the DOCTYPE. 
This seems extremely tacky, because it disregards all the other fun stuff in 
XHTML.

(I suspect REXML with 1.8 did not have this issue.)

If I should call Entity.new('nbsp', ' '), I don't understand how to .add 
that before the call to .new, and I don't understand how to easily add new 
HTML content to a preexisting Document object.

Any tips?
