You can't create an element for which there isn't a schema, except that
PyXB will treat DOM elements as wildcards which can be appended to an
xsd.anyType() instance instead of appending instances of an element derived
from some other schema. If you use the oseo bindings to parse that example
document into a Python instance, you'll see the raw DOM instances as the
content of the values element.
Normally you'd have schema for a namespace that is appropriate for your
application, and use those in something like:
pd.values = xsd.anyType()
pd.values.append(ds.processingLevel('1B'))
pd.values.append(ds.productType('ASA_IMS_1P'))
pd.values.append(ds.qualityOfService('STANDARD'))
AFAICT there is no schema for those samples (
http://www.opengis.net/oseo/1.0/dataset is not the same namespace as oseo
uses), so there is no ds module to use this way. While it's probably
possible to create the DOM content manually, it's not easy to do it in a
way that has the internal hints that lets PyXB generate documents with the
necessary namespace declarations (I just spent an hour on it and am giving
it up as not worth the time; sorry).
