Notice time

Notice time can become a complex attribute using the operation idea Raphael proposed and which is been used at Under Keel clearance. The construction can be like to following

Sub-attribute Camel Code Identifier multiplicity sequential
NTCHRS noticeTimeHours 0..* 1
NTCTXT noticeTimeText 0..1 n/a
OPERAT operation 0..1 n/a

That enabled us to model constructions like:
Notice is required 48, 24, 6 hrs in advance or when leaving the previous port whichever is less.
A further instance can be: Confirmation 2 hrs before arriving the xx-position.


Remark: Product specifications which allow multiplicity > 1 for this attribute should state whether the order of values has any significance and explain the significance.

Jens (BSH); I agree with that proposal. Looks pretty much better than our initial ideal of notice time (refer to the attribute section)
