# Similar to {Puppet::Pops::Binder::SchemeHandler::ModuleScheme ModuleScheme}, but relative to the config root.
# Does not support wildcard expansion.
#
# URI
# ---
# The URI scheme is `confdir:/[<FQN>]['?' | [?optional]` where FQN is the fully qualified name of the bindings to load.
# The referecence is made optional by using a URI query of `?` or `?optional`.
#
# @todo
#   If the file to load is outside of the file system rooted at $confdir (in a gem, or just on the Ruby path), it can not
#   be marked as optional as it will always be ignored.
