Hello Thorsten,
There is nothing wrong with your data.
I loaded your changed file without problems (albeit against v4.1.2) with a “normal” process command from the Tamino Interactive Interface. (The PROCESS command understands Data Loader syntax).
It loaded with Data Loader too after I had corrected your schema (collection and doctype were missing in the schemainfo), so that the schema define succeeded.
So what’s your problem now ?
As to your 2nd question: I would make one wrapper with all the DOCTYPE declarations to include in the documents.
All the best,
Hermann
