So one thing you can do is to do your own mapping to XML. In that case
you can come up with a more efficient XML representation.
Suppose the data is an array of ranges of doubles. A machine generated
encoding might be something like this:
<element><lower>123.1203892187</lower><upper>334.1231232232</upper></element>
<element><lower>123.1203892187</lower><upper>334.1231232232</upper></element>
<element><lower>123.1203892187</lower><upper>334.1231232232</upper></element>
etc.
But if you create the xml you could have:
<r l="123.1203892187" u="334.1231232232"/> which is significantly smaller.
But of course the data is still readable.

Differential encoding indeed has better performance. But it is not really
compressing SOAP message. Instead, it reduces both payload data and overhead
in the SOAP message.
But as far as I know, currently no popular SOAP toolkit supports
differential encoding.
