#
# Absolute paths are derived from the root object and can follow child<>
# or link<> properties. Since they can follow link<> properties, they
# can be arbitrarily long. Absolute paths look like absolute filenames
# and are prefixed with a leading slash.
#
# Partial paths look like relative filenames. They do not begin
# with a prefix. The matching rules for partial paths are subtle but
# designed to make specifying objects easy. At each level of the
# composition tree, the partial path is matched as an absolute path.
# The first match is not returned. At least two matches are searched
# for. A successful result is only returned if only one match is
# found. If more than one match is found, a flag is return to
# indicate that the match was ambiguous.
#
# @property: The property name to read
#
# Returns: The property value. The type depends on the property type. legacy<>
# properties are returned as #str. child<> and link<> properties are
