For guidance, see the example: myxmlre.xml and myxmlre.xsd
To receive full credit, your xml and schema must pass a validation test.
import xmlschema # google xmlschema and read.
my_schema = xmlschema.XMLSchema('class12_files/myxmlre.xsd')
my_schema.is_valid('class12_files/myxmlre.xml')
#What does the following do?
d = xmlschema.to_dict('class12_files/myxmlre.xml')
