4GL Access: RW

The NewValuesAllowed attribute specifies whether other values can be assigned to tags of this type, beyond those in the list or lists specified by the values keywords in the tag definition's TagValues array.

Default: FALSE

For example, an "IsArray" tag with a values keyword (TVS_BOOLEAN) typically would have NewValuesAllowed defaulted to FALSE, but a "client name" tag with a defined value list typically would have NewValuesAllowed set to TRUE.
