Today the tool take the version from the assembly (2.0.XX) and uses the major and minor version as part of the namespace and schema name.
Now, we change to version 2.1 and we don't want to change the namespace but the tool should have version 2.1.
In future, the tool version could be removed from the namespce.
Possiby the simpliest solution now is to introduce a configuration parameter in the config file,
Fixed in version 2.1
Introduced two config parameters one for namespace and one for schemaname.
