xmllint validation error “no DTD found” while using XSD
I'm trying to use xmllint to check my work while developing a basic XSD i.e. XML Schema schema. However it's giving me an error Validation failed: no DTD found. What am I doing wrong? My xmllint command: xmllint --noout --valid --schema simple.xsd lucas-basic.xml lucas-basic.xml:5: validity error : Validation failed: no DTD found ! > ^ lucas-basic.xml validates Test XSD file: <?xml version = "1.0" encoding = "UTF-8"?> <!--Generated by XML Authority.
