Bug description:
  [MIR] python-xmlschema

  [Availability]
  Currently in universe

  [Rationale]
  New versions of python-pysaml2 have a hard dependency on python-xmlschema.

  commit 3b707723dcf1bf60677b424aac398c0c3557641d from pysaml2
  (https://github.com/IdentityPython/pysaml2.git) introduced the
  dependency on xmlschema:

      Fix CVE-2021-21238 - SAML XML Signature wrapping

      All users of pysaml2 that use the default `CryptoBackendXmlSec1` backend and need to
      verify signed SAML documents are impacted. `pysaml2 <= 6.4.1` does not validate the SAML
      document against an XML schema. This allows invalid XML documents to trick the
      verification process, by presenting elements with a valid signature inside elements
      whose content has been malformed. The verification is offloaded to `xmlsec1` and
      `xmlsec1` will not validate every signature in the given document, but only the first it
      finds in the given scope.

  [Security]
  No security history

  [Quality Assurance]
  Package works out of the box with no prompting. There are no major bugs in Ubuntu and there are no major bugs in Debian. Unit tests are run during build.

  [Dependencies]
  Depends on python3-elementpath which is in universe.

  [Standards Compliance]
  FHS and Debian Policy compliant

  [Maintenance]
  Simple python package that the OpenStack Team will take care of

  [Background]
  The xmlschema library is an implementation of XML Schema for Python (supports Python 3.6+).

  This library arises from the needs of a solid Python layer for
  processing XML Schema based files for MaX (Materials design at the
  Exascale) European project. A significant problem is the encoding and
  the decoding of the XML data files produced by different simulation
  software. Another important requirement is the XML data validation, in
  order to put the produced data under control. The lack of a suitable
  alternative for Python in the schema-based decoding of XML data has
  led to build this library. Obviously this library can be useful for
  other cases related to XML Schema based processing, not only for the
  original scope.

  [MIR] importlib-resources

  [Availability]
  Currently in universe

  [Rationale]
  New versions of python3-pysaml2 have a hard dependency on importlib-resources - this is a backport of the importlib.resources module found in Python 3.9 or later.  Why do we need this module then?  Well for OpenStack it will be backported to Focal which uses a pre 3.9 Python version.
