As Martin told you, this is spec-compliant behaviour. Still, ElementTree 1.3
is expected to add a keyword argument "xml_declaration" in tostring() that
will let you override the default behaviour. lxml.etree already implements
that, BTW.

Some people propose just that if you really *want* a declaration. No need to
have it, though, as ET will create well-formed XML anyway.
