 are the two ways you should be getting descriptors) then the @type
 annotation is used to determine the document type...

 Except for when this is specifically checked before _parse_file() is
 called. :(
 https://gitweb.torproject.org/stem.git/blob/HEAD:/stem/descriptor/networkstatus.py#l1460

 {{{
     document_file = io.BytesIO(raw_content)
     published_line =
 stem.util.str_tools._to_unicode(document_file.readline())

     if published_line.startswith("published "):
       ...
     elif validate:
       raise ValueError("Bridge network status documents must start with a
 'published' line:\n%s" % stem.util.str_tools._to_unicode(raw_content))
 }}}
