Return type

Class

build_class_attributes(obj, instance)

build_class_extensions(obj, instance)

Build the item class extensions from the given ElementBase children.

build_data_type(instance, name, index=0, forward_ref=False)

Return type

AttrType

element_children(obj)

Recursively find and return all child elements that are qualified to be class attributes.

Iterator[Union[Attribute, Element, Restriction, Enumeration, Union, List, SimpleType]]

element_namespace(obj)

Return the target namespace for the given schema element.

In order:

• elements/attributes with specific target namespace
