Reference to an XML-Schema in xml document

My problem ist that i have the schema and it is now in the XPlorer too but i can``t insert the xml file because i have probably an error that say :
cannot be inserted as an instance; Schema not found; failed to locate schema for doctype “x” in collection “y”.

This is the beginning of my Schema:

<?xml version = "1.0" encoding = "UTF-8"?>

<xs:schema xmlns:tsd = “” xmlns:xs = “XML Schema”>

And this ist the reference to my schema that i have in my XML file.

I will be grateful if you can help me!

Best regards and thank you!

Not a very deep analysis, so there may be other problems as well …
But it looks like your schema reference has backslash\ instead of slash/ !?


Thank you very much Finn. I found the solution for the problem.

Best regards!
