Reusing Transformations

Translations Transformations which transform between two document structures are often usefully shared.
Fragmentation Transformations which focus on fragmentation are sometimes sharable (like slide creators), but transformation which route information to specific targets are often partially sharable or not sharable, depending on the binding.
Supplements Supplements where all the additional information is stored in the style sheet or other available documents are typically reusable. Processing which involves lookup in other resources is generally not reusable.
