The elements attributes select the root elements for file generation.
E.g. with the current semantics, elements="database/table" would create files for all table elements in the database root element.
However, this does not work for a typed model, because there the root element has no name. So there, we sould have to write elements="table" or elements="/table"
To have consistenht behaviour across typed and untyped model,s the secoond behavour will be used for both typed and untyped models.
