I think it would be useful to have a servlet with an "import like" functionality that would not store anything in the database but that would input XML documents (landing reports, production reports, user object, numbers requests, etc.) and output a toString of the document or appropriate error messages if there were defects in the input XML.
The intent would be to make it easy for customers to verify "well formed-ness" of eLandings XML documents, and provide another tool for technical support.
