    Schema versions and validation

    Starting from version 6.1, MRV files begin with a reference to the schema to which the file is conformed:

    <?xml version="1.0" encoding="UTF-8"?> <cml xmlns="http://www.chemaxon.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.chemaxon.com/marvin/help/formats/schema/mrvSchema_6_1_0.xsd" version="ChemAxon file format v6.1, generated by v6.1.0">

    In previous versions, MRV format didn't have a reference to a schema:

     <cml version="ChemAxon file format v6.0, generated by v6.0.0">

    or

    <cml>

    For these files, the recommended schema to use for validation is that of version 6.0.0.
