How to validate an METS document
To validate an METS document, you must include the following XML Schema in the METS document: http://www.loc.gov/mets/mets.xsd. Once you've included this schema in your METS document, XMLBlueprint XML Editor will support XML Completion for your METS document. To validate your METS document, open it in XMLBlueprint XML Editor and click XML > Validate.
To use this XML Schema, start your METS document with:
<?xml version="1.0" encoding="utf-8"?>
<?blueprint
namespace="http://www.loc.gov/METS/"
schema="http://www.loc.gov/mets/mets.xsd"?>
<document xmlns="http://www.loc.gov/METS/">
</document>
