Hello, I get this using the --postvalid option of xmllint with a valid XML file: $ xmllint --noout --valid article.xml $ xmllint --noout --postvalid article.xml article.xml:11: element xref: validity error : IDREF attribute linkend references an unknown ID "test" Document article.xml does not validate The ID exists in another file (section.xml), that is inbound via entity. The samples are attached. Bug or not a bug? A limitation of postvalid? Regards, Daniel
