"""
Test experiment for parse.
Add cardinality format field after type:
"... {person:Person?} ..." -- CARDINALITY: Zero or one, 0..1 (optional)
"... {persons:Person*} ..." -- CARDINALITY: Zero or more, 0..N (many0)
"... {persons:Person+} ..." -- CARDINALITY: One or more, 1..N (many)
REQUIRES:
parse >= 1.5.3.1 ('pattern' attribute support and further extensions)
STATUS:
IDEA, working prototype with patched parse module, but not accepted.
