    I am developing several definitions of catalog items and we want to define some elements that has an undefined cardinality, like a 1-n relationship. I can see from the documentation that max

    Hi Xose
    It rather looks as if your question was cut off in the middle of typing.
    I would guess, however, that you are interested in stating an undefined maximum bound for cardinality, e.g. on bundledproductofferingoptions entity.
    I suggest that you enter some arbitrarily large number (like 999, or even 9999999), for this purpose.
    Hope it helps.

    Yes it was typo there. My question is how to define an unbounded set of items with the max and min Cardinality included in the catalog (product, service and resource) definitions. I have seen that it is an integer value, so maybe a -1 could be a better option than 999999 because it is a fixed value that could interpreted always in the same way by the software to be created. 
    Also other negative values could help in create by example aggregated relationships where an item definition is shared by several other definitions and then it could be defined M-N relationships.
