@tmmartin ,

It sounds like you are using XML Tools (or similar) plugin for Notepad++. It is trying to tell you about an error in your XML and/or the DTD/Schema that it’s linking to.

This Forum is about Notepad++ itself, and cannot be an expert in – and should not be expected to provide help with – every possible thing you could type in Notepad++ … be it XML/XSD, HTML, C++, Python, JavaScript, cookie recipes, …

But let me google that for you – from what I can tell from those answers, it looks like your XSD file doesn’t define the attribute noNamespaceSchemaLocation for the hci_data element. I would start my research there, if I were you.
