[Python] Is it possible to validate an XML file against XSD 1.1 in Python?

I want validate an XML file against an XSD file using lxml.XMLSchema. But the problem is the XSD is in 1.1. So it doesn't work.

This is a part of the XML:

<?xml version="1.0" encoding="UTF-8"?>
<dictionary xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="!!assert.xsd">
<SizeType>10</SizeType>
</dictionary>


And this is its XSD file:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:element name="SizeType">
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:assertion test="$value = 10"/>
</xs:restriction>
</xs:simpleType>
</xs:element>
</xs:schema>


So, is it possible to validate an XML file against a XSD file that uses xs:assertion statements (1.1)?

I think this question is closely related to this: lxml with schema 1.1
