Hi Burak and Holger,
thank you both a lot for the good pointers and explanations.
It definitely helps, and I'll need some time to dig into.

Since a namedtuple is still a tuple this would trigger special-cased
sequence
assignment
namedtuple was contrived, in practice types it's more about nested
classes.
I'd probably forgo all this and simply use the glorious E-Factory to
create
structured data in assignments where needed
Tried E and am quite happy. Just discovered it automatically ignores
None arguments - that's very useful when python types have lot's of
optional attributes. Now I can simply write something like this
element = E.structured(
E.a(mytype.a) if mytype.a else None,
E.b(mytype.b) if mytype.b else None,
)
One new question: Is it possible to enforce an XSD type when
using E-Factories? Like in this again imaginary mini-DSL approach
ITEM_DATE = E(xsi_type="dateTime").item_date
ITEM_DATE(datetime.datetime.now()) # works, uses previously registered
custom objectify.PyType without guessing
ITEM_DATE("foo") # raises Exception because value can't be converted to
xsd:dateTime
Cheers
Tobias
