# For now, a pair of the path to an XML file and its modification time
# are used as a unique key. In theory, a checksum of the content could
# be used instead, and it could be more reliable, as modification time
# might not be updated in some insane filesystems correctly. However,
# in practice, checksums consume a lot of CPU time, so when the cache
# does not hit, the increased overhead is significant. In addition, it
# does rarely happen that two XML files in Business Manager contain
# the same data, so it may not be expected to have more cache hits
# with this approach.
#
# The disadvantage is that this wouldn't work with the archive format,
# because each entry in an archive does not have a mtime in itself.
# However, the plan is to have an archive to retain ZEXP directly
# instead of XML, so the idea of caching would be completely useless
# with the archive format.
