Error message given by validator:
"Start tag expected, '<' not found"

Possible causes for error:

• There is a redundant xml declaration (for example: <?xml version="1.0" encoding="UTF-8"?>) in the file. Precisely one xml declaration must be present on line 1 so that the file is well-formed according to xml specifications.
• You tried to validate your XML file with unsuitable schema pipe. For example pain.001.001.02 based file with e-invoice pipe or e-invoice message with sender info pipe.
• There are extra characters in the beginning of the file. For example "aaa<?xml version="1.0" encoding="UTF-8"?>
