src-resolve: Cannot resolve the name 'ds:Signature' to an 'element declaration' component
问题 I want to do schema validation using an XSD file. When I import the XSD file to Eclipse, without running the validation class, I have the following error: src-resolve: Cannot resolve the name 'ds:Signature' to an 'element declaration' component I am kinda new to XML vs XSD validation process. Although I have looked for similar questions on google, I couldn't figure out what's wrong here. The XSD file is as follows: <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org
