Re: adding CRLF to output XML file

The test map function is reporting that the output does not strictly match the schema. At runtime there is no validation of the map output, unless you explicitly code a schema validation or use one of the validating pipeline components.
The key question is does the map output match what your customer is expecting. If the answer is yes, then you have two options:
1. Ignore this error (you can even turn off output validation in the map properties so you never see this error)
2. Modify the schema to allow whitespace. This normally happens on records that contain no elements, just attributes. You can select these records and set  Mixed = true
