Difference between xs and xsd in XML schema file?

Question

What is the difference between the xs and xsd prefixes in XML schema files?

Answer 1

The xs: and xsd: are called namespace prefixes. They are declared using xmlns elements in the root element.

By convention people tend to choose either xs: or xsd: and map that to http://www.w3.org/2001/XMLSchema. Having both in a single document is confusing and should be avoided.

Check your xmlns declarations to determine what the namespaces are.
