Namespace propagation

[frazeradam]

This is close to where we need to be, but needs normalization applied to the order of attributes, for example:

<E:Body id="Body" xmlns:E="http://schemas.xmlsoap.org/soap/envelope/">

Should actually be:

<E:Body xmlns:E="http://schemas.xmlsoap.org/soap/envelope/" id="Body">

I am unsure of how to correct use existing code for this to not need to reinvent the wheel.

Closes #39 (assuming I can make changes to this to above the above mentioned issue)
