Madhan Neethiraj commented on ATLAS-2429:
-----------------------------------------

[~ayubkhan] - attribute is defined with 
{{"isOptional":false,"cardinality":"SINGLE"}}, which implicitly means minCount 
& maxCount are "1" i.e. minCount can't be less than 1 - as it not an optional 
attribute; maxCount can't be greater than 1 as the cardinality is SINGLE.

> ValuesMinCount and ValuesMaxCount in attributeDef always defaults to 1 for 
> any value.
