Simple function checking if the passed object contains a valid StationXML 1.0 file. Returns True of False.

The test is not exhaustive - it only checks the root tag but that should be good enough for most real world use cases. If the schema is used to test for a StationXML file, many real world files are false negatives as they don’t adhere to the standard.

Parameters:path_or_file_object File name or file like object.
