Yes there is a repository on LiveCycle server. It does allow you to see the correlation between fragments and templates. It will not report on the internals of the template (i.e. master pages, subforms individual fields etc). As the templates are all XML based you coudl create a system where when you store a template in teh repository that it is interrogated and all aspects that you want to track are stored in a DB. Then you coudl run reports on the data in teh DB.
No it does not ...you coudl expand teh DB idea to include these types of elements.
If you are interested in pursuing these types of questions you should be speaking to an account manager and an SE.
