Not properly objectifying attributes

Python : sys.version_info(major=3, minor=7, micro=4, releaselevel='final', serial=0)

= ISSUE =

It seems that when objectifying, attributes don't seem to be properly following the XSI schema.

= REPRODUCTION =
I have attached a tarball of a POC (there are some irrelevant function calls before it; they can be ignored). It demonstrates that text() objects are indeed properly identified and objectified as e.g. xs:positiveInteger => int() as according to their xsi type, but attributes with e.g. base type xs:positiveInteger are interpolated as type str().

./test.py in the tarball should get you a dump and it's commented with where it does what I... don't expect it to.

Is this expected?

Sorry; worth noting that the XSD and XML validate per xmllint(1):

[bts@cylon testxml]$ xmllint --noout --schema test.xsd test.xml
test.xml validates

and via lxml's validation as well (done from the same directory as the POC tarball):

[bts@cylon testxml]$ python
