# We're upgrading to edge because lxml comes with its own libxml2 which must match the system version for xmlsec to work
# We can remove this once python ships a docker container with a libxml2 that matches lxml
# Check lxml version with:
# import lxml.etree
# lxml.etree.LIBXML_VERSION
# Alternatively, build lxml from source to link against system libxml2: RUN uv pip install --system --no-binary lxml lxml
