How about promoting the query to a set of Python objects? eg,
path = Query(
ns.xmlns1.To / ns.xmlns1.mailto['name': 'Mrs Jones',
'test': '3'])
That's just off the top of my head as an example of the kind of thing
I mean. There is probably a better (more consistent, flexible, easier
to read, etc) spelling possible.
The advantages of this over strings is that you can break the query up
into multiple pieces, pass parts of it around as real, live objects with
introspectable APIs, allow for mutation of portions of the query,
re-arrange it, etc. All this is possible with strings too, just way
harder :)
