When SVN Code is checked out with Multiple Modules, and Tagging Option can be Defined with only one Generic URL TAG. All the Modules are to be Tagged as Mandatory and User dont have any Option to Uncheck or Not Tag the Unwanted Module. Cant Skip tagging for a single Module.
When using Multiple SVN locations, User should be given option to Choose which Module is to be Tagged and With customized "Tag Base URL" option.
E.G: when Adding a Module, provide a Check box "Include for Tagging". When checked, repo gets tagged if not checked, its skipped when performing Tagging on Successful build.
