If you're willing to transform the document before encoding (in a way  
that is unlikely to cause failure) you can also declare that <defs> is  
the required first child of the root element, then fold all content  
from other <defs> into it, plus all paint servers (linearGradient,  
radialGradient, solidColor) as well as filter, mask, clipPath, etc.,  
and make all of those forbidden elsewhere (instead of able to appear  
anywhere).

You can also normalise the style attribute (removing it completely),  
and kill most of the XLink attributes too.

There's a lot that can be done! As Taki says, relish!
