This is usefull if + inside of you program you know the struct will be valid, but need to + verify it has been assigned. + + omitempty + Allows conditional validation, for example if a field is not set with + a value (Determined by the required validator) then other validation + such as min or max won't run, but if a value is set validation will run. + (Usage: omitempty) + + dive + This tells the validator to dive into a slice, array or map and validate that + level of the slice, array or map with the validation tags that follow. + Multidimensional nesting is also supported, each level you with to dive will + require another dive tag. (Usage: dive) + Example: [][]string with validation tag "gt=0,dive,len=1,dive,required" + gt=0 will be applied to [] + len=1 will be applied to []string + required will be applied to string + Example2: [][]string with validation tag "gt=0,dive,dive,required" + gt=0 will be applied to [] + []string will be spared validation + required will be applied to string + NOTE: in Example2 if the required validation failed, but all others passed + the hierarchy of FieldError's in the middle with have their IsPlaceHolder field + set to true.
