Confusing message when modeling a String data type that doesn't have the length specified

When modeling a column defined as a String, but no length has been set, you get the warning message:

"Missing or invalid Length on column with a string/character datatype (See validation Preferences)"

This is confusing for several reasons:

• If its a warning, then the value must not be invalid
• It would be good to indicate what the default length will be when the length isn't set
