I've been trying to build a pepXML to mzIdentML converter and using this validator
to make sure my implementation is correct. Currently, I keep getting this error:
"Validation error in file './files/test-test.mzid' line 24231 column 13:
identity constraint key for element 'mzIdentML' not found"
I can't figure out what this error even means. I've asked the people who wrote the validator but I never got a reply.
If this error is specific to the validator and/or schema, then I guess I'll just delete this question, but if this is a general error that can occur when validating XML schema, then can someone please explain to me what this error means?
