[XML-SIG] problem in ElementTree SubElement

[Dan Gunter]

Right, in general XML processors don't care about attribute order (I 
don't know much about canonicalization but that does sound like the 
obvious exception). The XML Infoset specifically says they are an 
unordered set: http://www.w3.org/TR/xml-infoset/#infoitem.element ; so, 
if you care about order, rather than canonicalizing everything, maybe 
you should switch to using elements, e.g.

<date><month>02</month><day>06</day></date>
