Absolutely. For the specific case of a namespaced attribute, one way to do
it goes like this:
el = etree.Element('my_node_name')
el.set('{http://www.w3.org/2001/XMLSchema-instance}xsi', 'int')

For this specific namespace, and also a couple of other well-known
namespace URIs, lxml will use the "expected" prefix by default.
