XSD's compatible

[ashoktronix]

Hi Community,

As we know the xsd's for 2.1 and 2.2 are same with minor changes.
Can we validate 2.1.1 version of xml file against the 2.2 XSDs ? it is backward compatible ?

You mean the XSDs for ZUGFeRD?

You can do that, actually you may have to do it as there might be no indication which ZF Subversion you are dealing with. In the worst case you get a valid result for something which was invalid at the time and only later become valid.
Same applies for schematron. And please validate against both schema and schematron.
