It doesn't pass for me:

py> doctest.testmod(genshi.filters.transform)
**********************************************************************
File "/usr/lib/python2.4/site-packages/genshi/filters/transform.py",
line 29, in genshi.filters.transform
Failed example:
    html = HTML('''<html>
     <head><title>Some Title</title></head>
     <body>
       Some <em>body</em> text.
     </body>
    </html>''')
Exception raised:
    Traceback (most recent call last):
