What is the actual problem you're trying to solve?  If you just want to
force a namespace declaration in output (this is sually to support
QNames in content) the most well-known XML hack is to create a dummy
attribute with the needed prefix and namespace.  But this does not work
when you're trying to force a default namespace declaration.  Then
again, you generally can't use QNames in content with a default
namespace declaration.  So my guess is that you somehow got way off the
rails in your problem-solving, and you'll need to provide mre
background if you want help.

BTW, I recommend upgrading to Amara 1.1.7.  That branch will soon be
1.2, and I consider it more mature than 1.0 at this point.  The API's
also easier:

>>> import amara
>>> rwd = amara.parse('<pq:test xmlns="http://example.com/namespace" xmlns:pq="http://pq.com/ns2"/>')
