Talk:LIMTYP

raphael 22:15, 7 August 2009 (UTC) :

A new attribute Limitation Type is proposed. This attribute is intended to expand the expressiveness of CHALIM by allowing a more precise machine-readable specification of what is meant when a CHALIM is associated with some other object, for example 'negative limitations'. For example, to encode a limitation that applies only to vessels of draught greater than 12m, use LIMTYP=10 (included), MAXDRF=12; to encode a limitation that does not apply to vessels of draft greater than 12m, use LIMTYP=11 (excepted), MAXDRF=12. To encode a limitation that applies only at night, use LIMTYP=14 (new code meaning "applicable at night").

Concerning the enumeration: The first 4 (prohibited, required, permitted, recommended) are intended for use when CHALIM is attached to a facility to capture the fact that it is intended for use by vessels meeting certain limitations. The other two (included, excepted) are intended for use with regulations, etc.
